| 摘 要： | 考察了新疆夏子街钠基膨润土及有机化改性膨润土对水溶液中金属离子的吸附能力,重点研究了有机膨润土吸附水溶液中金属离子的工艺条件,以及有机膨润土的粒径和吸附次数对吸附效果的影响。实验表明:有机膨润土对金属离子的吸附能力明显优于原土;溶液的pH值对吸附效果影响较大;有机膨润的粒径对吸附效果影响较小;有机膨润土对Cr6+、Hg2+、Cu2+金属离子的吸附符合吸附等温方程。

| Abstract: | In this paper,the adsorption effect and optimum condition for adsorption of heavy metal ions in water with Xinjiang local bentonite and organobentonite were studied,the influence of heavy metal ion concentration in water,organobentonite particle size and adsorption number of times on thg adsorption effect was examined.It was shown that the effect of adsorbing heavy metal ions from water with organobentonite was obviously compared to bentonite.The effect of the pH value of solution on the adsorption was maximal,the influence of organobentonite particle size was less than that of bentonite,the logarithm adsorption isotherm of organobentonite was almost in line with heavy metal ion concentration in water.The adsorption isotherm was in accord with Freundlich equation. |
