摘要
金属硅样品经硝酸、氢氟酸溶解 ,用高氯酸冒烟、蒸发 ,除去硅后 ,采用铋磷钼蓝吸光光度法测磷 ,高碘酸钾氧化法测锰。该方法操作简便 ,测定速度快 。
The sample of silicon metal is dissolved with HNO 3 and HF,evaporated by HCIO 4 to remove silicon.Then,the phosphorus is determined with absorption spectrophotometric method using Bi-P-Mo blue and the manganese is determined with KIO 4 oxidation method.The analysis is proved to be rapid,accurate and easy to operate.
