本文研究了混合表面活性剂十二烷基硫酸钠-Triton X-100存在下,Ga(Ⅲ)与桑色素的荧光形成反应。在pH为0.7的HCl-NaAc缓冲溶液中,镓的检测限为1.7ng/ml,线性范围为2～120ng/ml,本法的灵敏度高,选择性好,采用适当分离方法消除干扰后可用于地质试样中镓的测定。
In this paper, the fluorescence reaction of Ga (Ⅲ) with morin was studied in the presence of sodium dodecyl sulfate-Triton X-100. The detection limit of gallium in HCl-NaAc buffer solution with pH 0.7 is 1.7ng / ml and the linear range is 2 ~ 120ng / ml. This method has high sensitivity and good selectivity and can be used to eliminate the interference by appropriate separation methods Determination of gallium in geological samples.
