摘要
提出了以数学校正扣除基体四价钒色泽对砷(磷)铋钼蓝色泽干扰的方法和校正磷对砷测定干扰的方法.应用于五氧化二钒中微量砷和磷的测定,结果准确、可靠.
It is reported in this paper that the interference of the background color due to vanadium (Ⅳ), and the interference of phosphorus in the determination of phosphorus and arsenic by the P(or As)-Bi-Mo hetero-molybdenum blue method, can be corrected by a mathematical method. The results obtained are accurate and reliable.
