Modification and Adsorption Performance of Agricultural Residues of Water Bamboo Leaves

This paper aims at dealing with the eutrophic water caused by the excessive phosphorus nutrient in the industrial detergents and agricultural fertilizers.The bio-sorbent-the cellulosic material of Water Bamboo Leaves(WBL) treated with FeCl₃ solution is prepared to improve the phosphorus removal capability.The adsorption results show that the bio-sorbent has much greater phosphorus removal capacity than that of natural WBL.By studying the effects of the different experimental parameters, the phosphorus removal capacity could achieve 4.36 mg/g at the conditions of pH value at 5.5, the time of the adsorption at 30 h.
