摘要
详细地研究了显色剂偶氮氯膦Ⅲ与Ti(Ⅳ)的显色反应和所形成的络合物,该络合物的λmax=690nm,表观摩尔吸光系数为1.47×105L·mol-1·cm-1,钛在0～1.0μg/ml内服从比尔定律,所拟定的方法能满意地用于还原用铁粉、粉末冶金铁粉和钢铁中微量钛的分光光度测定。
The color reaction of Ti with Chlorophosphonazo Ш was studied. When absorptiometer was used, the molar absorptivity is 1.47×105L·mol-1·cm-1. Beer’s law is obeyed for 0-1.0 ug /ml.This method has been used to trace Ti present in iron powder for deoxidization, and in iron and steel.
