摘　　要：以天然钠基膨润土(MT)为原料,采用溴化十六烷基三甲胺(CTMAB)和氯化十六烷基吡啶(CPC)进行有机改性及吸附丁基黄药试验研究。对有机膨润土CTMAB-MT和CPC-MT进行微结构表征,结果表明,CTMAB-MT和CPC-MT有机膨润土的d(001)峰值分别由原矿的12.41 nm增加到22.43 nm和21.46 nm,比表面积分别达到343.3068 m^2/g和295.4741 m^2/g,微孔结构增多。吸附试验结果表明,当吸附时间为6 h,吸附剂用量为8 g/L,反应温度为40℃时,各吸附剂对丁基黄药的去除率最高,CTMAB-MT对丁基黄药的吸附效果最佳,去除率达到89.85%。In this paper,natural Na bentonite(MT)was used as raw material,CTMAB and CPC were used as modification agent to study the organic modification and adsorption of butyl xanthate.The results show that the d(001)peak value of CTMAB-MT and CPC-MT organic bentonites increases from 12.41 nm to 22.43 nm and 21.46 nm respectively,and the specific surface area reaches 343.3068 m^2/g and 295.4741 m^2/g,respectively,and the micropore structure increases.The results of adsorption test showed that when the adsorption time was 6 h,the amount of adsorbent was 8 g/L,and the reaction temperature was 40℃,the removal rate of butyl xanthate was the highest.Meanwhile,the adsorption effect of ctmab-mt on butyl xanthate reached 89.85%.
