摘要
在硝酸介质中,罗丹明6G可大大增敏Ce(SO4)2氧化左羟丙哌嗪产生的化学发光,据此采用流动注射技术,建立了Ce(Ⅳ)-罗丹明6G-左羟丙哌嗪化学发光体系测定左羟丙哌嗪的化学发光新方法。在优化的实验条件下,该法测定左羟丙哌嗪的检出限为4.9×10^-7g/L,线性范围为0.8-80mL,对5ug/mL左羟丙哌嗪进行了11次平行测定,其RSD为3.8%。
A new chemil method combined with flow injection technique is developed for the determination of levodroproizine, based on the CL reaction of levodroproizine and Ce (Ⅳ) with Rh6G as an enhancement reagent. The liner range for levodroproizine is 0.8 - 80 ( ug/mL with detection limit of 4.9 × 10^-7g/L. The the relative standard deviation is 3.8% (n = 11) for 5 × 10^-6g/L levodroproizine. The synthetic samples are analyzed by proposed method for levodroproizine determination with satisfactory results. Based on studies of kinetic process and the spectra of CL and UV-vis absorption, a CL mechanism has been proposed.
