研究了在弱酸性介质中，锆（Ⅳ）催化过氧化氢氧化铬蓝黑Ｒ这一新的指示反应及其动力学条件，建立了一种高灵敏、高选择性测定痕量锆的新方法，方法检出限为３．７４×１０－１１ｇ／ｍＬ，线性范围０～１．１μｇ／２５ｍＬＺｒ（Ⅳ）．用于合金钢中痕量锆的测定，结果满意．
In a weakly acidic medium, zirconium (Ⅳ) catalyzed hydrogen peroxide oxidation of chromium blue black R this new indication reaction and its kinetic conditions, the establishment of a highly sensitive and highly selective method for the determination of trace zirconium The detection limit was 3.74 × 10-11g / mL and the linear range was 0 ~ 1.1μg / 25mLZr (Ⅳ). For the determination of trace zirconium in alloy steel, the results are satisfactory.
