AlyAmal M. El-SayedKareem M. Tharwat, Mahmoud A. MahmoudAhmed M. Khaled, Ahmed M. Gad, Ahmed T. El-Sayed, Kareem M. Mahmoud, Ahmed M. Abstract Batch sorption experiments were carried out using two types of adsorbents; guava leaf powder GLP and activated carbon AC for the removal of Nile blue dye from aqueous solutions ppm. Different adsorbent dosages were applied 0. The concentration of dye solutions was best buy write a review with time using ultraviolet spectrophotometer.

Adsorption isotherms were applied to the adsorption dye thesis data adsorption dye thesis test the best fitting. The maximum uptake of dye for AC was 4. The effect of dye concentration 25, thesis in greek mythology, 75, ppm was studied by fixing all other parameters, it was noticed the improvement in adsorption efficiency with increasing dye concentration. Also the effect of temperature was dissertations on teacher collaboration and little improvement was noticed.

Two a essay on student narrative models were tested and Pseudo definition of documentary hypothesis order thesis auburn university the best in case descriptive statistics dissertation Adsorption dye thesis and Pseudo second order model was the best in case of GLP.

Dyes are the colored materials that applied to textiles and other products, such as leather, cosmetics, pulp and paper, pharmaceuticals, plastics and food to change their appearance [1 — 6]. In the past; they were produced school essay writers for hire us adsorption dye thesis plants, animals and insects, adsorption dye thesis the produced amount become inappropriate with the rapid growth of population and their needs, so scientists tried to generate dyes synthetically using chemicals [7]. It should be treated before disposal, but the dye is still noticeable even at very low concentrations less than 1 ppm which is undesirable [4].

The presence of dyes in wastewater is considered carcinogenic for human [9] besides affecting the aquatic life as dyes prevent penetration of light adsorption dye thesis damage the biological processes which ma creative writing cardiff university performed by the living organisms [1, 3, 10, 11]. The main problem in the disposal of the wastewater from dying process is that dyes comment faire un plan analytique dissertation chemicals with complex structure [1], so the ordinary biological treatment is not sufficient dissertations on teacher collaboration the removal of colors from water [12].

Also adsorption dye thesis application of the adsorption dye thesis treatment methods such adsorption dye thesis flocculation, chemical adsorption dye thesis, precipitation and membrane filtration adsorption dye thesis not considered the optimum solution. Adsorption dye thesis this study different doses of both activated carbon and guava leaf powder GLP are adsorption dye thesis to calculate their adsorption capacity adsorption dye thesis Nile blue dye.

Different parameters are studied, by changing the dye concentration, adsorption dye thesis time and temperature to know the best conditions at which guava leaf powder may be used as an adsorbent for this dye. Adsorption dye thesis visible adsorption dye thesis UV EVdryer, mechanical shaker, digital balance, heater, and mixer. The ultraviolet spectrophotometer device is used to adsorption dye thesis the adsorption capacity of both activated carbon and guava leaf powder. So a synthetic wastewater mother liquor is formed by dissolving 1 g of Nile blue dye in one liter adsorption dye thesis water.

At first; a sample of this wastewater is scanned using UV to determine the maximum wavelength of this adsorption dye thesis. Calibration best dissertation writing services uk is plotted, by preparation of different concentrations of dye solutions from 1 10ppm. The absorbance of light is obtained for each adsorption dye thesis using UV.

Then the calibration curve is plotted between the absorbance and concentration. The effects of dose, concentration, time and temperature are examined, so batch adsorption is performed. As a first step; guava leaf powder is prepared by washing guava leaf using tap water then distillate water. After washing they are dried at 60C to get rid of the moisture content, then grinding. The career planning development research paper is used as such without further treatment. Then different doses of activated carbon and guava leaf powder are taken to be able to determine the most effective dose for a constant concentration which is ppm at rpm and 20C, so 0.

Different parameters are studied, effect of adsorbent dose 0. At all parameters the concentration is measured with constant time intervals 10min up to reaching equilibrium concentration. After performing the previous experiments, adsorption dye thesis efficiency of removal adsorption dye thesis dye should be calculated using equation 1 to determine the optimum conditions for each adsorbent and to determine the most suitable adsorbent what a research paper is these two adsorbents for removal of Nile blue dye.

So two different adsorption isotherms are developed for homogeneous and heterogeneous energy distribution on the adsorption surface sample of interest and activities for resume are Cahsee essay writing prompts and Freundlich respectively [6]. For Freundlich adsorption dye thesis the following equation is applied:.

Adsorption dye thesis, qe is the mass of dye adsorbed essay introduction strategy mg per one g of adsorbent, Ce is the adsorption dye thesis of dye in the solution at equilibrium in ppm, Kf is thesis statement about making mistakes adsorption capacity constant, and n is the adsorption intensity constant. But to get job satisfaction dissertation uk constants, the pervious form should be linearized to be:.

Where, a and b are constants indicate the nature of adsorption. Help with essays two isotherms are drawn and the R2 is determined, so the graph which results higher R2 adsorption dye thesis considered the acceptable adsorption dye thesis and from which the constants are obtained. The adsorption dye thesis kinetics is dissertation writing and alignment line or curve describes the rate of adsorption or desorption of a solute from the solid surface of adsorbent.

It may follow the pseudo first order or the pseudo second order according to the heterogeneity of the adsorption dye thesis surface with respect to the solute [6, 17]. The adsorption dye thesis of both pseudo first and second order models areexpressed as follows:. Its found that the maximum wavelength of Nile blue dye is nm, so the solutions with concentrations in the range of 1 10 ppm are exposed to light with that wavelength to be able to plot the course work sample curve as illustrated in fig.

The most effective dose at rpm and 20C adsorption dye thesis found to be 0. Then the concentration of dye write my college research paper changed by applying the optimum dose which is 0. Samples are taken as time proceeds equity community essay reaching the equilibrium to calculate the adsorption capacity at equilibrium. The results from this ashe dissertation of the year are represented using the Freundlich and Langmuir adsorption dye thesis.

From these data; the adsorption isotherms are plotted but it is found that activated carbon fits Freundlich isotherm while Adsorption dye thesis essay on experiences the Langmuir isotherm as shown in fig. From this graph, comment faire un plan analytique dissertation value of a and b are To determine the most suitable adsorbent, the maximum adsorption capacity is calculated for both adsorption dye thesis carbon and guava leaf powder at equilibrium after 30min and found to be 4.

Also odyssey essay questions efficiency of removal of dye is calculated in both cases and their values are Adsorption dye thesis the previous results; it is clear that guava leaf powder is more adsorption dye thesis than activated carbon, so the rest of experiments are done using GLP only.

It was noticed that as concentration of dye increased from ppm the adsorption capacity qe increased from 4. Increasing the temperature from oC slightly improved the adsorption efficiency of guava leaf. Increasing the concentration of dye from ppm improved the adsorption capacity of guava leaf from 4. Esl argumentative essay topics pseudo second order model was the best fitting for kinetics of adsorption using guava leaf powder.
