To effectively remove Diazinon (DZ), Amoxicillin (AMX), and Crystal Violet (CV) from aquatic environments, a novel granular activated carbon (GAC) modified with Polyethylene glycol 600 (PEG) was created manufactured. The chemical properties were investigated using variety of characteristic analyses, including FT-IR, XRD, FESEM, N2 adsorption/desorption. effectiveness GAC-PEG's adsorption for the removal DZ, AMX, CV assessed under conditions, pH 4-9 solution, 0.003-0.05 g doses adsorbent, 50-400 ppm starting concentration, reaction time 5-25 min. For adsorption, maximum capacity (Qmax) 1163.933, 1163.100, 1150.300 mg g-1, respectively. Langmuir isotherm described all data these experiments, pseudo-second-order well explains all-adsorption kinetics. Most contacts between molecules, electrostatic interactions, π-π hydrogen bonding, entrapment in CAG network used to carry out on GAC-PEG. retrievability prepared adsorbent successfully studies up two cycles without loss efficiency, it shown that can be efficiently separated.
