This study was focused on the sorption of chlorpyrifos from aqueous media utilizing
synthesized zinc oxide nanoparticles impregnated Pea peels (ZnONPs-IPPs) in batch mode
under the impact of pH of solution, dosage of sorbent, time of contact, temperature and initial
pesticide concentration. The prepared composite was characterized by SEM, EDX, Surface
area pore size analyzer and FTIR before and after sorption of chlorpyrifos. It was observed
that the sorption of chlorpyrifos depends upon pH and maximal sorption (56%) was occurred …
