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).
