海藻酸钠在重金属污染治理方面的研究

The Research of Sodium Alginate on Heavy Metal Pollution Control

概述了海藻酸钠在重金属污染治理方面的应用及国内外研究现状和发展前景,分别从海藻酸钠作为吸附剂直接吸附和作为固定化细胞的载体两方面分析了对重金属的去除效果及对固定化细胞的影响。分析表明,海藻酸钠以其特有的结构和性质在重金属污染治理方面有较好的应用,具有广阔的发展前景,同时指出了当前研究中存在的问题和今后的发展方向。

In the paper, the research status of sodiumalginate in home and abroad and the prospect of application in heavy metal pollution control were summarized. Both the effects on the removal of heavy metal ions and the effects of sodium - alginate on immobilized cell were analyzed from the sodium - alginate as the direct adsorbent and as the carrier of immobilized cell. Because the special structure and the property of sodium - alginate, the applications of sodium - alginate in the heavy metals pollution control were better and the developing prospects were broad. And then the problems and research direction of heavy metals pollution control in municipal rubbish landfill in the future were put forwards.
