摘要
以表面活性剂十二烷基苯磺酸钠改性天然沸石,对废水中甲基橙进行吸附,以紫外可见分光光度计分析最佳吸附条件,结果表明:在改性沸石的用量为20g/L、吸附时间为100min、温度为35℃、pH值为4.2时,十二烷基苯磺酸钠改性沸石对甲基橙溶液(10g/L)的吸附率达到了92.8%,吸附符合Langmuir等温方程。
Methyl orange solution of the waste water is absorbed with natural zeolite modified by SDBS in this study.UV-Vis spectrophotometer is then used to determine its maximum absorption capacity.The analysis results show that in the conditions of dosage of modified zeolite 20g/L,adsorption time 100min,35℃ and pH 4.2,the removal efficiency of methyl orange solution（10g/L） by modified zeolite could be up to 92.8%,According to the adsorption isotherm curves of methyl orange on modified zeolite,the regularity of adsorption fit Langmuir isothermal adsorption model.
