“…This trend could be explained as a consequence of partial overlapping or aggregation of adsorbent at higher biomass concentration, which results in a decrease in effective surface area for the adsorption. This is in agreement with result of Gao et al (2010), in which using granular sludge for the adsorption of acid yellow 17. However, there was no significant difference observed in amount of adsorption (p > 0.05), when adsorbent dosage decreased from 1.0 to 0.5 g L À1 .…”

Removal of Orange 7 from wastewater using natural adsorbent of Moringa Oleifera seeds were investigated.The effects of some operational parameters such as pH, the amount of biosorbent, initial dye concentration and temperature were examined. The present study revealed optimum conditions for the removal process which included dose of biosorbent (0.4 g), initial dye concentration (20 mg/L), initial pH (6) and temperature (25°C). The Langmuir and Freundich isotherms were applied for describing the biosorption equilibrium. The process was represented by the Freundich isotherm with a correlation coefficient of 0.94. The first-order, second-order and intra-particle diffusion kinetic models were implemented for demonstrating the biosorption mechanism and, as a result, intra-particle diffusion kinetics fitted best to the experimental data.

“…23 The values of q e , K 2 and h against C o in the corresponding linear plots of the pseudo-second order kinetic model were regressed in order to obtain the expression for theoretical MG and AY 17 concentration. These parameters could be expressed as a function of C o for MG and AY 17 as follows: (4) (5) (6) where A q , B q , A k , B k , A h and B h are constant for the respective equations and obtained through regression from the linear plots. The generalized predictive models for MG and AY 17 adsorbed at any contact time and initial dye concentrations within the given range with relationship of q t , C o and t can be expressed as follow: Theoretical model derived for MG and AY 17 was applied to obtain the adsorption capacity, q t at any given C o and t. A comparison between the experimental values and theoretical values was shown in Figure 10.…”

The effectiveness of using TiO 2 and corn cob films to remove Malachite Green oxalate (MG) and Acid Yellow 17 (AY 17) from binary dye solution was studied. The immobilization method in this study can avoid the filtration step which is not suited for practical applications. Batch studies were performed under different experimental conditions and the parameters studied involved initial pH of dye solution, initial dye concentration and contact time and reusability. The equilibrium data of MG and AY 17 conform to Freundlich and Langmuir isotherm model, respectively. The percentage removal of MG remained high after four sorption cycles, however for AY 17, a greater reduction was observed. The removal of both dyes were optimized and modeled via Plackett-Burman design (PB) and Response Surface Methodology (RSM). IR spectrum and surface conditions analyses were carried out using fourier-transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM) and atomic force microscope (AFM), respectively.
