摘　　要：大量研究表明:纤维素基生物质、甲壳素和微生物对水体中染料的吸附容量低于商品活性碳对染料的吸附容量;虽然壳聚糖对一些阴离子型染料有相当大的吸附容量,但由于其性能不稳定,因此难以获得大规模工业应用。关于生物质对其他有机污染物吸附性能的研究报道相对较少,说明这方面的研究有待于进一步深入和拓展。废弃皮胶原是一类来源极其丰富的生物质,近年来的研究发现:基于皮胶原研制的新型吸附剂对水体中的阴离子型染料和有机酸能有效去除,有可能在染料和有机废水处理方面得到应用。A large number of researches have indicated that the adsorption capacities of dyes on cellulose-based biomass, chitin and microbe were lower than those on commercial activated carbons from aqueous solutions. Although the adsorption capacities of some anionic dyes on chitosan were great considerably, the properties of chitosan were not stable enough to acquire the industrial application on large scale. The relatively fewer reports illustrate that there should be more profound and extended research concerned with the adsorption characteristics of other organic pollutants on biomass. Waste hide collagen is a type of very abundant biomass. The recent investigation has found that a novel adsorbent based on hide collagen had the effective removal of anionic dyes and organic acids from aqueous solutions and might have the potential usefulness on the treatment of dye and organic wastewater.
