A Mexican clinoptilolite-rich tuff was modified with the hexadecyltrimethyl ammonium (HDTMA) and used for the sorption of phenol and 4-chlorophenol. Whereas the zeolitic tuff had no affinity for phenol and 4-chlorophenol, the modified zeolite removed these organic compounds. The sorption behavior from aqueous solutions was studied by means of batch type and column experiments and isotherms were determined. It was found that the uptake was higher for 4-chlorophenol than for phenol.
一种富含斜发沸石的墨西哥凝灰岩用十六烷基三甲基铵（HDTMA）进行了改性，并用于吸附苯酚和4-氯苯酚。尽管沸石凝灰岩对苯酚和4-氯苯酚没有亲和力，但改性后的沸石去除了这些有机化合物。通过间歇式和柱实验研究了从水溶液中的吸附行为，并测定了等温线。结果发现，4-氯苯酚的吸附量高于苯酚。
