Because paracetamol is a medicinal substance, it is not biodegradable and will not degrade quickly. This will cause an environmental and health hazard because the residue will seep into wastewater, groundwater supplies, and eventually drinking water. In this study, has been prepared of low cost eco-friendly adsorbent Poly (Acrylic acid -acryl amide)/ Olive leaf plant, (AAc-AM)/OL hydrogel composite, the composite was prepared by free -radical polymerization by using a Specific ratio between hydrogels composite as a monomer and olive leaf plant. The resulting hydrogels were characterized by Fourier transform infrared (FTIR), thermo gravimetric analysis (TGA), and Field emission scanning electron microscopy (FESEM). A series of adsorption experiments were carried out under the Optimal conditions such as contact time and solution , pH ,the concentration of the drug ,and weight of the hydrogel composite .The adsorption capacity decrease from (8.11 – 19.3( mg.g-1 when the weight of the hydrogel composite increase from (0.025-0.15( g, demonstrating the quantity of adsorption increased with increased pH ,that increased adsorption capacity with continuous in a base  medium. Adsorption isotherms of hydrogel composite are well described by the Freundlich, Langmuir and Temkin isotherm. The maximum sorption capacities of paracetamol onto Hydrogel is 17.857 mg g-1. https://jns.kashanu.ac.ir/article_113942_46beeae7aa303b7ca4186ebdf73b715f.pdf
