    Modification and Adsorption Performance of Agricultural Residues of Water Bamboo Leaves

      摘要
    • 摘要: 以农业废弃物茭白叶为原料,利用FeCl3溶液进行浸渍改性,制备了茭白叶生物吸附剂,研究了吸附剂吸附富营养化物质磷的行为.利用场发射扫描电镜研究了原始茭白叶与生物吸附剂表面形貌变化,重点研究了被吸附溶液pH值、FeCl3溶液的质量浓度、生物吸附剂的粒度等因素对磷吸附能力的影响.研究表明,生物吸附剂的粒度越大,吸附能力越强.采用50 g/L的FeCl3溶液对原始茭白叶进行改性,被吸附溶液pH值为5.5,吸附时间30 h,片状生物吸附剂的吸附能力可以达到4.36 mg/g.

       

      Abstract: 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.
