摘要
研究了以SMP蒙脱土为原料,以十八烷基三甲基溴化铵(STAB)为插层剂制备有机蒙脱土,采用红外光谱对蒙脱土和有机化蒙脱土的结构进行表征,也研究了有机蒙脱土对水中苯酚的吸附性能。结果表明:有机蒙脱土对水中苯酚的吸附性能明显优于原土,在pH=10、温度为20℃、有机蒙脱土投入量为4g/L条件下吸附80min,苯酚吸附率达79.12%。
Organic montmorillonite was preparated using SMP as raw material,octadecyl trimethyl ammonium bromide(STAB) as organic intercalation reagent.The product was characterized by FTIR.The adsorption performance of the organic modified montmorillonite for phenol in water was studied at the different adsorption condition.The results show that the adsorption capacity of the organic modified montmorillonite was surperior to the unmodified montmorillonite obviously.The adsorption capacity may reach 79.12% at the conditions of pH=10,20 ℃,addition of 4 g/L and the adsorption time of 80 min.
