溶液的表面张力测定显示,增效剂的加入使油酸的临界胶束浓度(cMC)降低,相当于降低了药剂的作用浓度。吸附量检测表明,表面活性剂促进了油酸在矿物表面的吸附,使油酸的吸附量增加。关键词:一水硬铝石;油酸;浮选;Tween-20;增效剂中图分类号:TD91LIUSan-jun,QINWen-qing,LIUWei,WANGJun,ZHANGYan-sheng(SchoolofMineral...
The lowest regions in the plots of both foam height and half‐life of foam are with the Tween‐20 and BSA mixed solution, which locate around the CMC value of Tween‐20. It was concluded from the experimental results that the replacement between Tween‐20 and BSA is the main factor in ...
