锯末吸附污染物的研究进展

Research progression on absorbing pollutants by sawdust

锯末是价格低廉且来源广泛的工农业废弃物,其作为吸附剂在污染治理中越来越受到青睐。本文首先介绍了锯末吸附作用的原理和影响吸附效果的因素,然后概述了锯末在染料、重金属、油类等水体污染物和气体污染物处理中的应用研究状况,最后对未来锯末吸附污染物的应用研究进行了展望。

Sawdust,a kind of widely available and inexpensive agricultural and industrial waste material,is currently being paid more and more attention as an important adsorbent in environmental improvement.Firstly,the adsorption mechanism and influential factors were discussed.Secondly,application of sawdust to dyes,various heavy metals,organic matters and gaseous pollutant was reviewed.Finally,Some useful guidelines were drawn for further application.
