摘要
本文以间氨基苯基荧光酮为显色剂,非离子—两性混合表面活性剂为增敏剂,以巯基棉为W、Sn等高价元素的吸附分离剂,建立了高灵敏度、高选择性的测定钛的新光度法。其表观摩尔吸光系数为1.46×10~5,大量的两价元素及W、Mo、Sn、Ge等高价元素均不干扰钛的测定,用于各种合金钢中微量钛的测定。
A highly sensitive chromogenic reaction of titanium with m-aminophenylfluorone and emulsifying agent-OP and DDMAA has been investigated.The molar absorptivity is 1.46x105L . mol-1 . cm-1. Interferences of W,Mo,Sn can be eliminated by adsorption and separation with sulfhydryl cotton fiber, The method has been applied to determine microamounts of titanium in various steels,
