比较分析了不同酸、碱及酸碱复合改性凹凸棒石对模拟含磷废水的吸附净化性能，并探讨了不同改性对凹凸棒石磷吸附性能的影响．结果显示，当凹凸棒石与质量分数为9％的盐酸在固液比为1∶2条件下改性，磷吸附效率达53.59％．N aO H先与凹凸棒石1∶1混合均匀后焙烧改性，再将碱改性后的凹凸棒石与质量浓度为9％的盐酸在固液比为1∶2再进行改性，吸附效率高达99％以上即碱酸复合改性的凹凸棒石极大地提高了其对磷的吸附效率．

The purify and adsorb function of palygorskites modified by different acid ,alkali and acid-alkali compound to the simulation waste water which contained the phosphorus were compared and analyzed . The adsorb phosphorus function of palygorskites which modified by different substances was investiga-ted initially .The results show that the adsorption effect of phosphorus is improved when the mass ratio of palygorskites and hydrochloric acid solution which contains 9% double distilled water is 1∶2 ,the ad-sorption productivity is 53.59% .The mass ratio of alkali modified palygorskites and hydrochloric acid solution which contains 9% double distilled water is 1 ∶2 ,the adsorption effect of phosphorus is ex-tremely enhanced by the acid-alkali compound palygorskites and the adsorption efficiency achieves as hig h as 99% .
