交联粘土矿物吸附特性研究(Ⅵ)——铝锆交联土对废水中有机物的吸附

Study on the adsorption of cross-linked clay minerals (Ⅵ): adsorption aluminium-zirconium cross-linked bentonite for organism in wastewater

比较了不同交联膨润土对废水中有机物 (以化学需氧量 COD表示有机物含量 )的吸附 .结果表明 :铝锆混合交联膨润土吸附剂 (简称 AZB吸附剂 )对 COD有较好的吸附性能 .当吸附时间为 3 0 min,废水 p H=4.1 2 ,每升水中的用量为 9g时 ,AZB对 COD的吸附容量为 5 5 .6mg/g,吸附效率为 89.6% .

Adsorptions of different crosslinked bentonites for organism (expressed as COD) in wastewater are compared in this paper . The results show that a AZB adsorbent containing aluminiumzirconium has higher adsorption for COD. When 9 g AZB is added in 1 L wastewater and adsorptive time is 30 min at pH=4.12,the adsorbility and absorption rate of AZB are 55.6 mg/g and 89.6 % for organism (COD )
