酸化凹凸棒石的制备及其对苯胺的吸附性能
Preparation of Acidified Palygorskite and Its Adsorption Performance for Aniline
摘要
Abstract
Natural palygorskite was acidified with different concentration of hydrochloric acid.The acid-ified palygorskite was characterized by XRD,SEM,BET,FTIR and ZATA potential.Under different process conditions,the adsorption performance of acidified palygorskite treated with different concen-tration of hydrochloric acid,was evaluated by removal of aniline in water.When the activation concen-tration of hydrochloric acid was 6mol·L-1 ,the pH value of the aniline solution was 6,the initial mass concentration of aniline was 50mg·L-1 ,the amount of adsorbent was 0.5g,the temperature was 30℃,the adsorption time was 240min,the acidified palygorskite could acquire better adsorption activity and remove more than 75.2% of aniline.In addition,the adsorption behavior of aniline over a-cidified palygorskite was more suitable to be described by pseudo-second-order kinetic model.关键词
