将3-烯丙氧基苯嵌蒽酮与丙烯酸胺和N,N’-亚甲基双丙烯酰胺一起共聚在硅烷化含乙烯基团的石英玻片上,制成了可传感药根碱的光极膜。药根碱能快速可逆挥灭光极膜的荧光。在1.00×10-5~4.00×10~(-4)mol/L范围内,膜对药根碱响应呈线性关系。由于共价固定化作用阻止了敏感试剂的流失,传感器显示出好的稳定性。常见无机阴、阳离子及一些常见药物对测定无显著干扰。传感器用于尿样中药根碱测定的回收率在102%~105%之间。
The 3-allyloxybenanthraquinone was copolymerized with acrylamide and N, N’-methylenebisacrylamide on a silanized ethylene group-containing quartz slide to make a detectable jatrorrhizine Light film. Juncine can rapidly reversibly volatilize the fluorescence of the photoelectrode. In the range of 1.00 × 10-5 ~ 4.00 × 10 -4 mol / L, there was a linear relationship between the membrane and jatrorrhizine. Because covalent immobilization prevents the loss of sensitive reagents, the sensor shows good stability. Common inorganic anion, cation and some common drugs on the determination of no significant interference. The recovery rate of the sensor for the determination of jatrorrhizin in urine samples was between 102% and 105%.
