实验采用氢氟酸分离含钛冶金物料中硅,硼酸碳酸钠混合熔剂熔融的方法分解试样,解决了磷元素测定由于基体多样导致的酸溶消解难,碱熔过滤沉淀速度慢的问题,同时避免了磷元素被沉淀物吸附的损失问题,分离硅使得硫酸浸出速度快且有效地防止了钛的水解,选择高锰酸钾为氧化剂保证氧化完全。优化实验条件后,磷的检测的范围在0.005%~0.5%,方法的相对标准偏差小于8%,回收率在90%~110%之间,结果令人满意。
實驗採用氫氟痠分離含鈦冶金物料中硅,硼痠碳痠鈉混閤鎔劑鎔融的方法分解試樣,解決瞭燐元素測定由于基體多樣導緻的痠溶消解難,堿鎔過濾沉澱速度慢的問題,同時避免瞭燐元素被沉澱物吸附的損失問題,分離硅使得硫痠浸齣速度快且有效地防止瞭鈦的水解,選擇高錳痠鉀為氧化劑保證氧化完全。優化實驗條件後,燐的檢測的範圍在0.005%~0.5%,方法的相對標準偏差小于8%,迴收率在90%~110%之間,結果令人滿意。

Experiment using hydrofluoric acid separation containing titanium metallurgy material of sil -icon, boric acid sodium carbonate mixed flux fusion method of decomposition of sample to solve the phosphorus determination due to the matrix leading to a variety of acid dissolution difficult , alkali fu-sion filtering sedimentation speed is slow , while avoiding the phosphorus to sediment ceiling attached to the loss, separation of silicon makes sulfuric acid leaching speed is fast and effective to prevent the hy -drolysis of titanium .The choice of potassium permanganate as oxidant guarantees complete oxidation . The range of phosphorus detection is 0.005%~0.5%, the relative standard deviation of the method is less than 8%, the recovery is 90% ~110%, and the results are satisfactory .
