Biosorbent of rice husk was utilized to evaluate the removing of paracetamol from aqueous medium by sorption process (batch-concept); studying the influence of several experimental parameters as biosorbent dose, contact time, change of temperature; also studying the behaviour of the equilibrium isotherm of paracetamol into the rice husks and comparing the data with different isotherm models. Pseudo-second order equation and Langmuir model were best suited fordata experience. With increasing temperature the sorption process increased; suggesting that the process is endothermic in nature. FTIR test was tested before and after sorption for the purpose of showingthe presence and number of the functional groups ofparacetamolbinding on to the tested sorbent.
