摘要
根据+4及+5价钒与磷钼钨可形成不同杂多酸的特性,研究了采用分光光度法同时测定+4及+5价钒。该法选择性好,抗干扰性强,灵敏度高,简便、快速,测定结果准确。
The determination of multivalent vanadium is researched by spectrophotometry based on the characteristic of ＋4 and ＋ 5 vanadium forming P-Mo-W-V heteropolyaeid with P, Mo,W. The method has the advantages of highly selectivity, sensitive and highly anti-interference to impurity ions and rapidly and easily. The determination results is accuracy.
