基于亚硝根对溴酸钾氧化罗丹明6G的催化及锌粉使硝酸根还原为亚硝酸根的原理,建立了同时测定亚硝酸根和硝酸根的荧光动力学法,用于饮用水、质控水样、饮料中硝酸根及亚硝酸根的测定,测定下限分别为0.074ng NO_2~-/ml和0.25ng NO_3~-/ml.
Based on the catalytic effect of nitrite on the oxidation of rhodamine 6G by potassium bromate and the reduction of nitrate to nitrite by zinc powder, a fluorescence kinetic method for simultaneous determination of nitrite and nitrate was established for drinking water, quality control water Determination of nitrate and nitrite in beverages, the lower limit of determination of 0.074ng NO_2 ~ - / ml and 0.25ng NO_3 ~ - / ml.
