随着近代工业的迅猛发展，染料废水及重金属废水对生态环境和人类健康带来广泛而持久的危害。作为生物质的一类，农林废弃物具备廉价、比表面积大和官能团丰富的特点，其作为吸附剂在水处理中的应用得到了广泛研究，其中酸改性农林废弃物提高其吸附性能是当前的研究热点，但酸改性后所产生的滤液一般被直接排放，容易造成二次污染。本研究利用磷酸（phosphoricacid，PA）改性笋壳（bambooshootshell，BSS）后所得滤液中的酸溶纤维（BSSfiber，BSSF）与壳聚糖（chitosan，CS）和Fe3O4粉末共混均匀并经过三聚磷酸钠（sodiumtripolyphosphate，STPP）交联后...With the fast development of modern industry, wastewater pollution of dyes and heavy metals is becoming more and more serious, causing a series of environmental and health problems. Agricultural and forestry waste (AFW), one category of biomass, is suitable for water treatment because of its low cost, large specific surface area and abundant functional groups. Acid modified AFW as an adsorbent use...学位：工学硕士院系专业：化学化工学院_工程硕士(化学工程)学号：2062013115149
