特性吸附与半胶束吸附
specifical adsorption and hemi-micelle adsorption
texing xifu yu banJ旧oshu xifu特性吸附与半胶束吸附(speeifieal adsorp-tion and hemi一mieelle adsorption)矿物一水界面的吸附的两种形式。特性吸附是因矿物表面与溶液中某种组分(离子或分子)有特殊的亲和力而产生的吸附，也称特殊吸附。特性吸附不仅可以改变电位的数量而且还可以改变电位的符号。例如，刚玉(A12O3)在NaZSO‘或RSO;Na(烷基硫酸钠)溶液中，电动电位随溶液浓度的增大由正值逐渐减小，直至变为负值，说明刚玉对50矛一或RSO不离子有特殊的吸引力。半胶束吸附是水溶液中的表面活性剂在矿物表面产生的吸附，当吸附量达到一定值以后，由于烃基的缔合作用，表面活性剂的离子或分子在矿物表面上形成紧密的吸附层，这类似于溶液中形成的胶束结构，但所形成的“胶束”与溶液中形成的胶束不同，只有二维空间，故称这类吸附为半胶束吸附。矿物表面对胺类捕收剂的吸附，当胺的浓度较大时，常可以产生半胶束吸附。 (龚焕高)
