| 摘 要： | 采用盐酸对天然沸石进行改性处理,在不同条件下,研究了酸改性沸石对废水中硫化物的吸附。结果表明,改性斜发沸石对硫化物有较好的吸附效果,吸附时间、温度、pH值和沸石用量是影响吸附的主要因素。采用30%双氧水作为斜发沸石的再生剂,可使其再生重复使用。

| Abstract: | Natural zeolite was modified using hydrochloric acid and its ability of adsorption sulfide in wastewater under different conditions was studied. The results indicate that modified zeolite can improve adsorption of sulfide. Some factors are affecting adsorption including adsorption time, temperature, pH and zeolite consumption. Regeneration of clinoptilolite can be realized using 30% hydrogen peroxide solution. |

| Keywords: | modified zeolite absorption sulfide regeneration |
