快速检测净水器中活性炭的吸附效果

Rapid Test on Adsorption Effect of Activated Carbon in Water Purifier

对于采用氯及其制剂进行消毒的自来水,净水器中活性炭不仅吸附水中有机物,也吸附水中余氯。活性炭对有机物的去除率与对余氯的去除率有很好的相关性。通过测定余氯去除率来表征对水中有机物的去除能力,即间接判断净水器中活性炭吸附效果是可行的。机理研究表明,活性炭吸附有机物,有效吸附面积下降,导致活性炭对余氯去除率下降。本研究提供了一种可快速、简便而有效的检验活性炭吸附效果的方法。

activated carbon indirectly. The study of mechanism showed that adsorption of organic substances on activated carbon caused decreasing effective adsorbing surface area and also decreasing removal rate of residual chlorine. This study provided a rapid, convenient and effective method for testing adsorption effect of activated carbon in water purifier. For using chlorine as tap water disinfectant, activated carbon in water purifier could not only adsorb organic substances but also adsorb residual chlorine. The removal rate of activated carbon to organic substances is well correlated to the removal rate of residual chlorine. To detect the residual chlorine in tap water will be able to indicate the ability of removing organic substances, and to determine the adsorption effect of
