摘要
通过离子交换反应，将天然钙基膨润土制成铜基和ＨＤＴＭＡ有机膨润土。铜基土能直接吸附黄原酸根离子，同时对其氧化反应产生催化作用。有机土对黄药及其氧化产物黄原酸亚铜与双黄药均产生吸附。两种改性土联用则能显著提高黄药的去除能力。
y ion exchange reaction,the naturalCa-bentonite is changed into Cu-obentniteard HDTMA organbentonite. The Cu-ben-tonite can adsorp xanthated ion directly,giving catalysis to its oxidization reaction.The organbentonite can adsorp xanthate andits oxidization products──xanthatedCuprous and dixanthate. The combination ofthe two modified bentonite can improve theremoval capacity of xanthate.
