摘要
用盐酸对天然沸石进行改性得到酸改性沸石,通过静态吸附实验研究了酸改性沸石对废水中甲醛的吸附性能。研究表明在293 K时,酸改性沸石对甲醛的平衡吸附量为255 mg/g,最佳吸附pH值为6.5,吸附平衡时间为2 h。
The acid modified zeolite were prepared by hydrochloric acid and natural zeolite.The adsorption of acid modified zeolite to formaldehyde was studied through static experiments.The results indicated that when pH was 6.5,the statically saturated adsorption capacity was 255 mg/g at 293 K.It spent 2 h to reach adsorption equilibrium.
