“…Also the results show that increasing the initial concentration of MB increases the initial adsorption rate (h = k 2 q e 2 ). Similar results have been previously reported (Belaid et al, 2013). It was stated that the quantity of the rate of adsorption k2qe was exactly the inverse of the half-life of adsorption process (t1/2).…”

Low cost agricultural waste adsorbents can be viable alternatives to activated carbon for the treatment of contaminated wastewater. Sugarcane Bagasse, an abundant agriculture waste in Egypt, was used in the present study to prepare activated carbon. Batch adsorption experiments were conducted to study its effectiveness to remove cationic dye methylene blue from aqueous solution. The effects of initial dye concentrations, agitation time, solution pH and temperature on methylene blue dye removal were investigated. The optimum pH value for the maximum percentage removal of the dye was 7. Adsorption isotherms were determined and modeled with Redlich-Peterson, Langmuir and Freundlich equations at 20 °C. The kinetic data were analyzed using Pseudo-first order, pseudo-second order. The mechanism of the adsorption process was determined from the intraparticle diffusion model. Thermodynamic parameters such as standard enthalpy (ΔH°), standard entropy (ΔS°) and free energy (ΔG°) were determined. The equilibrium data were best fitted to the Redlich-Peterson isotherm model .The adsorption kinetics was found to follow the pseudo-second-order kinetic model with good correlation coefficient. The positive ΔH• value indicated that the adsorption process was endothermic in nature. The results revealed sugarcane bagasse activated carbon could be employed as a low-cost alternative adsorbent in wastewater treatment.

“…Therefore, this review provide comprehensive information on the application of activated carbon for the treatment of dye and study the effect of adsorption factors towards dye removal. solubility in water [29] or else by their particle charge during dissolution such as anionic dyes (reactive, direct and acid dye), cationic dye (basic dye) and also non-ionic dye (disperse dye) [30]. In addition, anionic and cationic dye including in water soluble dye while non-ionic dye is in the categories of water insoluble dye.…”

Abstract. Industrial company such as textile, leather, cosmetics, paper and plastic generated wastewater containing large amount of dye colour. The removal of dye materials are importance as the presence of this kind of pollutant influence the quality of water and makes it aesthetically unpleasant. As their chemical structures are complicated, it is difficult to treat dyes with municipal waste treatment operations. Even a small quantity of dye does cause high visibility and undesirability. There have been various treatment technique reviewed for the removal of dye in wastewater. However, these treatment process has made it to another expensive treatment method. This review focus on the application of adsorbent in dye removal from textile wastewater as the most economical and effective method, adsorption has become the most preferred method to remove dye. The review provides literature information about different basis materials used to produce activated carbon like agricultural waste and industrial waste as well as the operational parameters factors in term of contact time, adsorbent dosage, pH solution and initial dye concentration that will affect the process in removing textile dye. This review approach the low cost and environmental friendly adsorbent for replacing conventional activated carbon.

“…But, some authors [57,58] incorrectly attribute these sequential adsorption kinetic curves to one kind of adsorption site, (Figure 10), (7) Data of plateau region can't be used in kinetic and thermodynamic calculations. Nevertheless, during study of rapid adsorption process, some authors [59] reported data of plateau region rather than data of regions before it, ( Figure 11) and (8) Under alkaline conditions, metal ions participate as metal hydroxide. But, in some cases it was wrongly reported [60] that adsorption capacity …”

At first, the KASRA model and KASRA equation are discussed [1][2][3]. KASRA is an abbreviation for "Kinetics of Adsorption Study in the Regions with Constant Adsorption Acceleration". The KASRA model was presented by Samiey [1] in 2013 and is based on the following assumptions: (1) each time range with constant adsorption acceleration, is named a "region", (2) there are two regions before attaining plateau region, (3) the boundaries between the first and second regions and the second and third (plateau) regions are named "starting second region" (abbreviated as ssr) and "kinetics of adsorption termination" (abbreviated as kat) points, respectively and are determined by the KASRA equation, (Figures 1-4). Due to different features of the first and second regions, parameters obtained from a kinetic equation (such as the pore-diffusion, Avrami and Elovich equations, etc.) for these two regions are different from each other and the related equations for these regions come different pathways to the point q t =0 at t=0 (or q 01 according to the KASRA model). It is good to say that KASRA is a Persian word meaning king. AbstractIn different concentration ranges of adsorbed species, various interactions occur between them and surface adsorption sites and there are different regions in an adsorption isotherm. In the common method for study of adsorption process, all of these regions are considered as one region and thus there are concerns regarding using adsorption equations. In this work, based on the KASRA and ARIAN regional models, a new method is presented for analysis of adsorption kinetic and thermodynamic data, respectively. The KASRA and ARIAN models are three-and four-region models, respectively and adsorption equations are used on the basis assumptions used in these models. According to the ARIAN model, adsorption binding constant of each region of an adsorption isotherm is different from the other regions. On the other hand, based on the kinetic KASRA model and ideal-second-order (ISO) equation, during the adsorption in each initial adsorbate concentration, different interactions occur between adsorbate species and adsorbent surface sites and thus the observed adsorption binding constant is an average value of these binding constants.
