Metabolites of A Novel Antibiotic Bitespiramycin in Rat Urine and Bile

A sensitive analytical method to identify active metabolites of bitespiramycin in rat urine and bile was developed by liquid chromatography-electrospray ionization tandem mass spectrometry(LC/ESI-MS^n).Bitespiramycin and its major active metabolites in rat urine and bile were isolated and identified as M1 serial(spiramycin Ⅰ，Ⅱ，Ⅲ),M2 serial(platenomycin A1,josamycin and leucomycin A1) and M3 serial(deisovalerylplatenomycin A1,deisovaleryljosamycin,deisovalerylleucomycin A1).     

膨润土对亚甲基蓝的吸附性能研究

为将膨润土作为消化道粘膜保护剂提供依据，本文研究了钠质，钙质膨润土对亚甲基蓝的吸附性能。研究了在20℃下的吸附动力学，测试了肿附速率常数，绘制了20℃下各型膨润土的吸附等温线，并求得其饱和吸附量。结果表明，20℃时钠质膨润土的吸附速率要快于钙质膨润,各型膨润土的吸附行为符合Langmuir方程，钠质膨润土的饱和吸附量qm为86．51mg/g，与粘膜保护剂思密达比较接近，而钙质膨润土吸附能力相对较弱。     

酚醛型吸附树脂对水体系中吡啶和N,N-二甲基苯胺的吸附性能研究

研究了酚醛型吸附树脂在水体系中对吡啶和N，N-二甲基苯胺的静态和动态吸附行为．结果表明，在水中树脂对吡啶和N，N-二甲基苯胺的吸附主要以疏水吸附机理进行；吸附吡啶和N．N-二甲基苯胺的初始阶段，即达到38．3～48．9％平衡吸附时，吸附速率数据和半经验速率方程很吻合：酚醛型吸附树脂等温吸附吡啶和N，N-二甲基苯胺的平衡吸附数据符合Langmuir方程，相关系数在0．99以上，酚醛型吸附树脂吸附吡啶和N，N-二甲基苯胺属单分子层吸附：用80％的乙醇溶液作洗脱剂来洗脱吸附吡啶已达饱和的JDW-2树脂，效果是很理想的．在3．6个床体积内洗脱率达91．52％，4．8个床体积内洗脱率达到94．85％。表明酚醛型吸附树脂具有优良的洗脱性能．     

以Cyanex272为载体的乳状液膜迁移和分离铅的研究

用Ｃｙａｎｅｘ２７２－Ｓｐａｎ８０－甲苯乳状液膜体系研究了铅的迁移行为，确定了铅迁移的适宜条件。在此条件下，许多常见离子如Ｃｕ＾２＋、Ｃｏ＾２＋、Ｎｉ＾２＋、Ｃｄ＾２＋等均不迁移，Ｈｇ＾２＋迁移率很低。因此Ｐｂ＾２＋能与这些离子得到快速且完全的分离。这对分析测定及三废处理等工作具有实际意义。
