In this research,the Near Infrared Spectroscopy was used to scan the spectrum of Sulfamethazine in duck's liver powder.

中文摘要本研究以近红外光技术(Near Infrared Spectroscopy，NIR)针对鸭肝粉中磺胺二甲嘧啶(Sulfamethazine，SMT)之残留量进行扫描光谱。

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...

以磺胺二甲嘧啶为模板分子，分别用甲基丙烯酸和4乙烯基吡啶为功能单体，二甲基丙烯酸乙二醇酯为交联剂，采用牺牲硅胶法合成了磺胺分子印迹聚合物，通过静态吸附实验，系统研究了不同单体对聚合物识别性能的影响；Scatchard分析表明，以甲基丙烯酸为单体的聚合物具有较高的吸附能力，其离解常数Kd为959×10-4mol/L，最大表观结合位点数Qmax为3070μmol/g。

Pharmacology function】Huang An the AN oxygen Mi Ding be in the Huang An medicine to suppress the germ a very strong kind of the function to synthesize anti-virus medicine, because of it with for germ to synthesize folic acid demand of to ammonia Ji the benzene be sour to have likeness on the structure, exchange with PABA to contend for two hydrogen folic acids to synthesize Mao, bar the germ synthesize two hydrogen folic acids to synthesize Mao, bar the germ synthesize two hydrogen folic acids, end influence nucleic acid protein of synthesize, repress thus germ of growth breed, to variety E-and E+very strongly repress a function.

磺胺间甲氧嘧啶是磺胺类药物中抑菌作用极强的一种合成抗菌药物，因其与细菌合成叶酸时所需要的对氨基苯酸在结构上具有相似性，与PABA兑争二氢叶酸合成酶，阻碍细菌合成二氢叶酸合成酶，阻碍细菌合成二氢叶酸，最终影响核酸蛋白质的合成，从而抑制细菌的生长繁殖，对多种E-及E+有很强的抑制作用。
