Abstract:

Some kinds of activated carbon selecting methods for treating natural water at present, such as activated carbon inspection method, micro column rapid breakthrough method (MCRB), tannic acid value and caramel decolorization rate determination and the method of determining the relationship between the pore size distribution and adsorption capacity, have been reviewed. Based on the analysis of the present research status both in China and abroad, it is hoped to find out some accurate, highly efficient and convenient methods of activated carbon selecting methods in order tomeet the demands of water treatment field.

Key words: activated carbon selecting, micro column rapid breakthrough, caramel decolorization rate, tannic acid value, pore size distribution

摘要：

评述了目前几种天然水处理用活性炭的选择方法：活性炭检验法、微型柱快速穿透(MCRB)法、丹宁酸吸附值和焦糖脱色率测定法、测定活性炭的孔径分布与活性炭吸附性能的关系法。通过剖析国内外的研究现状，以期寻找准确、高效和方便的活性炭选择方法，以适应水处理行业的需求。
