已有文献报导,用示波极谱法在钛-铜铁试剂-溴酸钾和钛-六次甲基四胺-铜铁试剂体系中,对痕量钛进行了测定,灵敏度尚嫌不足,我们发现,在pH 值6.8的硫酸钠-
It has been reported in the literature that the determination of trace titanium in the system of titanium-copper-iron-potassium bromate and titanium-hexamethylenetetramine-copper-iron by the oscillopolarographic method has not yet achieved sufficient sensitivity and we find that , Sodium sulfate at pH 6.8 -
