摘要
基于亚硝酸根对溴酸钾氧化邻苯二酚紫使其褪色的催化作用，建立了一种测定痕量亚硝酸根的新方法，研究了其动力学条件，测定了反应级数和表观活化能。测定范围为０．２～３．５μｇ／１０ｍＬ。方法选择性好，迅速简便，用于水中和蔬菜中亚硝酸根的测定。
A new sensitive method for the determination of trace nitrite was developed,based on nitrite as a catalyst.The optimum kinetic conditions were discussed and the concentration of nitrite was linear in the rang of 0 2 3 5 μg/10mL.The proposed method is simple,rapid,selective and convenient to determine nitrite in water and vegetables with good results.
