摘要
在pH1.81的缓冲介质中,水溶性苯胺蓝与十六烷基三甲基溴化铵作用并形成离子缔合物,产生以383nm为特征峰的共振光散射(RLS)增强信号。其RLS增强程度与水溶性苯胺蓝浓度成线性关系,检出限和线性范围分别为1.28nmol/L和0.013~54.0μmol/L,据此建立了痕量水溶性苯胺蓝的共振光散射分析方法。
In pH 1.81 buffer solution, water soluble aniline blue (AB) and cetrimonium bromide (CTAB) interacted to form ion-association complex, which resulted in greatly enhanced resonance light scattering (RLS) signals at 383 nm. It was found that the enhanced RLS intensity ( AI_RLS) at 383 nm was proportional to the concentration of water soluble aniline blue. The determination limit and the linear range of water soluble aniline blue were 1.28 nmoI./L and 0. 013 ~54. 0 μmol/L. Thus a new method for the determination of trace water soluble Aniline blue could be established accordingly.
