摘要
制备了KH-550改性凹凸棒土材料,研究其对Cr6+的吸附性能,并考察不同制备条件对改性凹凸棒土吸附Cr6+的影响。研究结果表明,用硅烷偶联剂KH-550改性剂用量为(酸改性凹凸棒土质量为6.0g)4.5mL、反应时间为2h、反应温度为40℃时,制备的改性凹凸棒土对Cr6+的吸附率最大,污水处理效果最佳。
KH-550 modified attapulgite was prepared to study the-effect of different preparation conditions on the adsorption properties for Cr6＋. The results showed that the most appropriate amount of KH-550 was 4.5mL, while the a- mount of attapuigite was 6g. The best reaction time was 2h, and the optimal reaction temperature was 40℃.
