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 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
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 ZPCpH value of the surface of carbonated coal
derived from the cherry cores is within (10), meaning that the surface charge is positive within the value of this
acidic function. Also, 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 adsorbed 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, Eiovich,
and Doben).
