Removal of acetamiprid pesticide from the agricultural waste as charcoal derived from the cherry seeds by adsorption process

Abstract

Water pollution by agricultural fertilizers, whether they are nitrogenous, phosphatic or potassium, the use of which is increasing due to the limited arable soil, and the trend towards expansion of intensive agriculture to increase the productivity of the farmer of food with the steady growth of the population. The objective of this research is to assess the adsorption potential of Cherry seeds (CS) as an adsorbent for the removal of acetamiprid from aqueous solutions. The sorption process was examined in terms of its equilibria and kinetics. Batch adsorption experiments were conducted to evaluate the removal of these dyes onto CS waste over a wide range of operating parameters such as initial dyestuff concentration, equilibrium Time, adsorbent dosage, pH, and temperature. The experiments for the adsorption of acetamiprid pesticide from its aqueous solution using carbonated charcoal the derivative of cherry cores, one of the successful methods of adsorption of a Acetamiprid pesticide, where the removal value R was about (54.5%) are the focus of this report (solid-liquid adsorption). Various experimental conditions were tested, such as contact time (equilibrium) and the best capacity for adsorption was at (2.5 h), acid function, and the results showed that the optimum capacity for adsorption was at pH =10, The results indicate that, the weight of the adsorbing surface (0.2 g) is the best in terms of the amount of adsorption, and the results showed an increase in the amount of charry coal with the increase in the initial concentration, the kinetic adsorption results it is subject to a pseudo-second-order kinetic equation. The study included the choice of applying isothermate models (Langmuir, Freundlich, Temkin, Harkins-jura, Elovitch, and Dupin).
