查询词典 triphenylmethane

In pH 5.3-6.8 Britton-Robinson buffer medium, Cefotaxime sodium can react with HgCl2 to form 1:1 anionic chelate, which can further react with basic triphenylmethane dye such as crystal violet, methyl violet, ethyl violet, brilliant green, iodine green, methyl green and malachite green to form ternary ion-association complexes. As a result, the resonance Rayleigh scattering spectrum was enhanced greatly.

在pH为5.3~6.8的Britton-Robinson缓冲溶液中，头孢噻肟钠与HgCl2形成摩尔比为1：1的螯合阴离子，它能进一步与结晶紫、甲基紫、乙基紫、亮绿、碘绿、甲基绿和孔雀石绿等碱性三苯甲烷类染料反应形成三元离子缔合物，导致共振瑞利散射的显著增强。
