【摘要】 本文研究了以邻硝基苯基荧光酮－溴化十六烷基三甲基铵为试剂的流动注射分光光度测定钛的新方法。该方法分析频率达到１００次／ｈ，线性范围为０～１．０μｇ／ｇ方法重性好，用于合金钢及纯铝中钛的测定，结果满意。更多还原

【Abstract】 new method of flow injection analysis withmanifold convergence utitlizing model 72l spectropho-tometer for thedetermination of micro amount of tita-nium using o-nitrophenylfluorone andcetyltrimethylammonium bromide has been developed.The optimal reaction conditions and instru-mental parameters have been selected in detail.Themethod is simple, rapid,sensitive and selective. It hasbeen usedtodetermine micro amount of titanium inalloy steels and pure aluminium samples with repro-ducible results.更多还原
