| 摘 要： | 在弱酸性Britton-Robinson缓冲溶液中,阿曲库铵(AB)与二氯荧光素(DCF)、二溴荧光素(DBF)、二碘荧光素(DIF)形成离子缔合物,引起这3种染料的最大吸收峰明显降低,并在532 nm(DCF体系)、540 nm(DBF体系)和551 nm(DIF体系)处出现新的吸收峰.在一定范围内,AB浓度与吸光度的改变值(ΔA)成良好的线性关系,不同体系的摩尔吸光系数(ε)在9.95×103~1.22×105L/(mol.cm)之间.据此,提出了测定AB的新分光光度法,并考察了体系的光谱特征、适宜的反应条件和共存物质的影响.将该方法用于尿样中AB的测定,回收率在97.6%~104.4%之间.
