The use of low-cost adsorbent papaya leaf was investigated as a replacement for current costly methods of removing methylene blue dye (MB) from the aqueous solution. The adsorption equilibrium was determined as a function of contact time, initial adsorbate concentration, and solution pH. The adsorptive uptake of MB increased with increasing the initial MB concentration and solution pH. The adsorption isotherms were correlated with a comparison of linear and nonlinear regression analysis. Langmuir isotherm model provided the best-fit for the adsorption of MB onto papaya leaf, with a maximum monolayer adsorption capacity of 231.65 mg/g. This locally available adsorbent was found to be low cost and promising for the remediation of textile wastewater.

Adsorption of methylene blue onto papaya leaves: comparison of linear and nonlinear isotherm analysis

The use of coconut shell activated carbon (CSAC) as a potential adsorbent for malachite green (MG) dye from aqueous solution was investigated in this study. The effect of various factors, such as initial dye concentration, contact time, pH, and solution temperature were studied. The interaction between dye molecule and CSAC absorbent was strongly influenced by the pH of the solution. Maximum adsorption of MG was obtained at pH 6.5, while, the point of zero charge (pHzpc) of CSAC was obtained at pH 6.1. The Langmuir, Freundlich, and Temkin isotherms were used to describe the adsorption equilibrium of the MG. The maximum monolayer adsorption capacities, Qm, were increased with increment in temperature. The kinetics of adsorption followed a pseudo-second-order kinetic model. The intraparticle diffusion model was evaluated to determine the mechanism of the adsorption process. Based on the Boyd plots, the adsorption of MG on the CSAC absorbent was mainly governed by film diffusion. Thermodynamic parameters, such as G, H, and S were determined and it was found that MG adsorption on CSAC was spontaneous and endothermic in nature. The conducted reusability test disclosed the decreasing CSAC performance from 98% MG removal down to 89% MG removal after 5 consecutive adsorption/desorption cycles.
