利福平分子印迹聚合物的制备及其吸附行为

以利福平为模板分子、甲基丙烯酸为功能单体、乙二醇二甲基丙烯酸酯为交联剂，制备了利福平分子印迹聚合物.采用平衡结合方法和Scatchard模型评价了该聚合物的结合特性，考察了其吸附行为.结果表明，利福平分子印迹聚合物中形成了两类不同的结合位点，得到高亲和力结合位点的离解常数和最大表观结合量分别为31.5μg/mL和23.34mg/g，低亲和力结合位点的离解常数和最大表观结合量分别为9.22μg/mL和12.86mg/g.实验结果显示，利福平分子印迹聚合物对利福平呈现出了高的选择吸附特性

molecularimprintingflowinjectionchemiluminescencemethodfordeterminationofdoxycyclinehydrochloride

Doxycycline hydrochloride can enhance the chemiluminescence of potassium ferricyanide and luminol in alkaline medium. So a molecular imprinting-flow injection chemiluminescence method for the determination of doxycycline hydrochloride was established by using doxycycline hydrochloride-imprinted polymers as recognition material and potassium ferricyanide and luminol as detection system. Doxycycline hydrochloride-imprinted polymer was synthesized using methacrylic acid as functional monomer and ethylene glycol dimethacrylate as cross-linker. The linear range is 9.0 x 10(-7)-6.0 x 10(-5) g.mL(-1) and the detection limit is 3.2 x 10(-7) g.mL(-1). The relative standard deviation for 6.0 x 10(-6) g.mL(-1) of doxycycline hydrochloride was 3.5% (n = 9). This method has been successfully applied to the determination of doxycycline hydrochloride in tablets and in urine samples

脉冲频率对铝基PEO涂层隔热性能的影响规律及作用机理

在硅酸盐体系下使用等离子体电解氧化(PEO)技术在ZL109铝合金试样表面进行了陶瓷化处理,并采用SEM、XRD、DSC、激光导热仪等方法系统地研究了脉冲频率变化对PEO涂层热性能的影响规律及作用机理。研究表明,脉冲频率主要通过影响涂层的相结构组成及显微结构从而引起隔热性能的变化。当频率为200 Hz时,PEO涂层的热导率最低,为0.113 W/(m·K)
