Study on the Fluoresecence System of Tosufloxacin Tosylate-Aluminum and Its Analytical Application
Pages: 59-62
Year: Issue:  1
Journal: Acta Scientiarum Naturalium Universitatis Neimongol

Abstract: 铝(Ⅲ)在HAc- NaAc缓冲介质中,与甲苯磺酸妥舒沙星生成稳定的络合物从而使甲苯磺酸妥舒沙星的内源性荧光显著增强,据此建立了测定甲苯磺酸妥舒沙星的荧光新方法.该体系在最大激发波长λex=365nm,最大发射波长λem=420nm时,甲苯磺酸妥舒沙星浓度在3.2×10-8~9.6×10-6 mol· L-1范围内与荧光强度呈良好的线性关系,最低检出限为8.3×10-9 mol·L-1,回收率在9...
