摘要
利用双十八烷基二甲基氯化铵(DOTAC)对膨润土(BET)进行改性,合成新型阳离子表面活性剂/膨润土(DOTAC/BET)吸附剂体系.通过热分析、红外光谱等方法对吸附剂结构性能进行表征,并研究了对苯酚的吸附性能.结果表明,当ρ(苯酚)=1.0g/L时,振荡时间60min、环境温度25℃、吸附剂用量0.30g、水中pH=7,DOTAC/BET吸附剂对苯酚的吸附量达到49.39mg/g.
Bentonite(BET)was modified into a cationic surfactant(DOTAC/BET)system by using double eighteen alkyl dimethyl ammonium chloride(DOTAC).The structure was identified and studied by thermal analysis(TG-DTA)and infrared spectroscopy(FT-IR)method.Study on the performance of DOTAC/BET for adoption phenol showed that the adoption value was 49.39mg/g under the following conditions:the initial concentration of phenol was 1.0g/L,the dosage of adoption agent 0.30 g,the oscillation time of 60 min,the temperature 25℃,and the pH value 7,respectively.
