摘要
在草酸介质中 ,变色酸与钛生成红色络合物 ,在 490nm波长处测量吸光度 ,借此测定钛铁中钛。此法简便、准确 ,完全能满足生产的需要。
In the medium of oxalic a cid a red complex of chromotropic acid with titanium*$ was formed T he absorbance was measured at 490n m The content of titanium in ferro titanium could be determined The pr oposed method is easy to operate a nd accuracy.
