| 摘 要： | 为降低饮用水原水中残余Al^３＋的含量，研究了盐酸（改性剂）浓度及吸附条件对凹凸棒原土和盐酸改性凹凸棒吸附性能的影响。结果表明：盐酸改性凹凸棒对Al^3＋的吸附效果优于凹凸棒原土；当盐酸浓度为6mol／L时，改性凹凸棒对Al^3＋的吸附效果最好；在水体系的pH值为7．0，改性凹凸棒用量m（改性凹凸棒）／v（水）]为8g／L，吸附时间为3h的最佳吸附条件下，可使饮用水中残余Al^3＋的质量浓度由0．264mg／L下降为0．118mg／L。

| Abstract: | The effects of hydrochloric acid(modifier) concentration and adsorption conditions on the adsorption capability of raw soil of attapulgite and hydrochloric acid modified attapulgite were studied to reduce the residual aluminum content in the raw water of drinking water.The results showed that adsorption effect of the hydrochloric acid modified attapulgite to Al3+ was betteer than that of raw soil of attapulgite,and attapulgite modified by 6 mol/L hydrochloric acid had the best adsorption capacity.At the opt... |
