摘要
报导了环己烷、庚烷等的加溶对非离子表面活性剂 (吐温 - 80 )液 -固析相分离的影响 ,使小分子显色剂对甲酰基偶氮变色酸 ( CAp F)、偶氮胂 ( Arsenazo )和配合物在低温下就易从盐水溶液相富集到表面活性剂固相 ,萃取率达95%。并对环己烷、庚烷的加溶机理及温度的作用做了探讨。
Effect of solubilizing of cyclohexane and heptane on liquid solid liberation of phase separation Tween salt water system was reported. In low temperature, small molecule developer( p formbenzenylazo chromotropic acid and arsenazo Ⅰ) and its complex were easily extracted and enriched into surfactant phase. The mechanism of liberation phase separation of non ionic surfactant was studied.
