摘要
采用氢氟酸分解试样、硝酸氧化Ti(Ⅲ)为Ti(Ⅳ),无需分离钛,氯化银比浊法测定海绵钛中0.00X%～0.X%的微量氯离子,相对标准偏差为2.02%～4.88%,方法简便快速,结果准确。
Adopting hydrofluoric acid to decompose samples and nitric acid to oxidize Ti（Ⅲ） to Ti（Ⅳ）,turbidimetry of silver chloride was used to determine the chlorine ion（0.00X%～0.X%） in titanium sponge with no separation of titanium,RSD was between 2.02%～4.88%,the method is simple,fast and can obtain exactly results.
