biosorption study of 4-nitrophenol onto pineapple peel

The aim of this study is to investigate the utilization of pineapple peel as a biosorbent for the removal of 4- nitrophenol from water. the effect of main parameters such as initial 4- nitrophenol concentrations, ph, dosage of pineapple peel, temperature and contact time were carried out on biosorption of 4-nitrophenol. results showed biosorption reached equilibrium within 30 min. as results, the amount of 4- nitrophenol biosorption increased by increasing of pineapple peel dosage and ph.
