【摘要】 本文以十二烷基硫酸钠(SDS)为代表研究了阴离子表面活性剂作为青霉素萃取工艺的破乳剂的破乳能力及其作用规律.结果表明,在较低的浓度下 SDS 就有较好的破乳效果,但在一定条件下 SDS 明显影响青霉素的萃取率.更多还原

【Abstract】 The effects of anionic surfactant——sodium dodecyl sulfate(SDS)on demulsifi- cation during extraction of penicillin G from the filtrate of fermentation broth are reported in this paper.Results show that demulsification by anionic surfactant SDS is very good even at low concentration.But inhibition of SDS on extraction of penicillin G is observed at higher concentration of SDS low pHs.更多还原
