胶束增溶光度法用于钛的测定已有多篇报导。本法将非离子表面活性剂tritonX-100用于钛-苯芴酮显色体系,摩尔吸光系数ε_(534)=1.72×10~5,钛量在0～10微克/50毫升,呈现良好的线性关系。铁、钒、铬、锆、锡的干扰,采用抗坏血酸、DCTA消除,方法用于铝合金中微量钛及镁质耐火材料中二氧化钛含量的测定。实验部分一试剂钛标准溶液:0.1mg Ti ml~(-1),称取纯二氧化钛0.1668克,于铂坩埚中用焦硫酸钾10克熔融。用硫
Micellar solubilization spectrophotometry has been reported for the determination of titanium. In this method, the nonionic surfactant tritonX-100 is used in the color system of titanium-benzofluorenone. The molar absorptivity ε_ (534) = 1.72 × 10 ~ 5, the amount of titanium is 0 ~ 10 μg / Linear relationship. Iron, vanadium, chromium, zirconium, tin interference, using ascorbic acid, DCTA elimination method for the determination of trace titanium and magnesium in aluminum alloy refractory titanium dioxide content. Experimental part of a reagent titanium standard solution: 0.1mg Ti ml ~ (-1), weighed 0.1668 grams of pure titanium dioxide, 10 grams of potassium pyrophosphate in a platinum crucible melting. With sulfur
