Optimization of absorption process for exclusion of carbaryl from aqueous environment using natural adsorbents

Abstract The equilibrium adsorption of carbaryl insecticide was examined by several easily available natural adsorbents like Alluvial soil, Pistia stratiotes biodust, Lemna major biodust, neem bark dust, and eggshell powder to remove carbaryl from an aqueous environment. The batch experiments were achieved as different operating parameters. For overall validity of the process, response surface (RSM) and artificial neural network (ANN) models were used. The maximum amount of Carbaryl adsorbed onto different adsorbents is presented in this chapter. Adsorption isotherms, kinetics, and thermodynamics of the process were also provided. Finally, results showed that neem bark dust (NBD) has the maximum adsorption capacity of carbaryl. Because NBD is easily prepared, it can be a used as effective adsorbent for removal of the insecticide from contaminated water.
