摘要
在分析我国淡水资源严重污染的基础之上,提出以生物质作为吸附剂用于水中污染物的去除;指出我国生物质材料来源丰富,综合利用有助于环境的改善。分别考察了秸秆类、壳类、叶类等生物质材料改性制备方法,对其改性后的吸附能力作了综合分析;通过物理或化学法对生物质材料进行相应的处理,可以有效提高其吸附能力;对改性生物质吸附剂对水中污染物的吸附性能进行了归纳,对其改性机理作了简要分析;明确了现阶段改性生物质吸附剂研究的现状,提出了未来改性生物质吸附剂可能的研究方向。
it was put forward for the removal of pollutants in water by using biomass as adsorbent based on the analysis of the water resources pollution seriously in our country. It was pointed out that the biomass sources were abundant and comprehensive utilizations which could contribute to the improvement of the environmental quality. The biomass materials, such as the straw, shell and leafy, preparation and modified methods as adsorbent were investigated, and the adsorption capacity of modified biomass was studied comprehensively. The adsorption capacity of modified biomass, which was modified by physical or chemical method, could be effectively improved. The adsorption effieency for pollutants in water were summarized, the modified biomass as adsorbent and the modification mechanism were briefly analyzed. It had been investigated clearly about the current research situation of modified biomass as adsorbent and research direction which should put possible forward in the future
