【摘要】 以钙基膨润土为原料,钠化后用溴化十六烷基三甲铵(CTMAB)进行有机改性,制得有机膨润土。在单因素吸附实验的基础上,采用L16(44)正交实验法对有机膨润土吸附水中苯胺的工艺条件进行了优化研究。结果表明,当矿物的粒径小于74μm、振荡速度为150 r/m in、吸附液为25 mL,并且以此三者为固定因素时,其优化工艺条件为有机膨润土投加量2.0 g,温度40℃,pH 7,吸附时间1.5 h。更多还原

【Abstract】 The organobentonite was made from natural Ca-bentonite sample,firstly Na-modified and then by hexadecyl trimethyl ammonium bromide（CTMAB）.The optimum technological conditions of sorption of aniline on organobentonite in aqueous solutions were investigated with orthogonal L₁₆（4⁴）experiments.The results indicated that the organobentonite particle size is less than 74 μm、the stirring speed is 150 r/min、the volume of solution for sorption is 25 mL and the above three factors act as invariable ones, the optimum technological conditions are as follows: the dosage of organobentonite 2.0 g,the sorption temperature 40 ℃,pH 7,the sorption time 1.5 h.更多还原
