| 摘 要： | 1引言硝酸盐广泛存在于各种环境水体中。当饮用水中硝酸盐浓度过高时,可能对人体健康造成危害;地表水中硝酸盐大量积累,则可能引起藻类过度繁殖,溶解氧耗竭,水质恶化。目前,检测硝酸盐的最常用方法是将硝酸盐还原为亚硝酸盐,再经重氮偶联反应后由分光光度法进行测定[1]。此类方法已较好地与流动分析技术相结合,广泛应用于测定环境样

| Abstract: | An environmental friendly method was developed based on reversed flow injection(r-FIA) with UV-induced reduction of nitrate to nitrite and spectrophotometric detection.Sample or standard solutions were mixed with a phosphate buffer solution containing diethylenetriaminepentaacetate(DTPA),and then passed through a UV reduction reactor equipped with an 8 W low pressure mercury lamp,where the nitrate was reduced to nitrite.The formed nitrite was detected with spectrophotometric method through Griess reaction.L... |
