摘要
Abstract
In this paper ,two kinds of modified diatomite adsorbents were prepared and their decoloriza-tion performance was studied comparatively through the methods of the direct decolorization of solution and column chromatography .The results showed that temperature increase of solution of reactive dyes was beneficiated to increase the decolorization efficiency of the two modified diatomite .At neutral pH value , the decolorization percent of the two modified diatomite was the lowest ,but it went up with the increase or decrease of pH value .The decolorization performance and cost of the diatomite modified by cationic poly-mer was much more superior to that of the diatomite modified with anion exchange resin .关键词
