摘    要:采用盐酸溶解铝合金试样,高氯酸冒烟将磷氧化成正磷酸在0.42mol·L盐酸介质中,用抗坏血酸还原为铋磷钼蓝进行光度测定。经过条件试验,基体不干扰测定。对合成试样进行测定,回收率在91%-105%之间。该方法操作简便,结果准确可靠。

关 键 词:铝合金    分光光度计

Abstract:Thesample was dissolved by HCL Phosphorus was oxidized to phosphorie acid, which was then reduced to molybdobismuthy phosphoric acid in mediator of 0.42 mol·L-1 HCl by ascorbic acid and then phosphorus was determinated by spectrophotometric method. The associated sample was also determinated. Recovery rate is at 91%-105%. The method is easy to operate and has high accuracy and precision.
Keywords:aluminium alloy  phosphorus  speetrophotometry method
