摘　　要：建立了自制浮选器富集、分光光度法测定羊角铺水源水中痕量亚硝酸盐氮的方法,介绍了试验的注意事项。方法在0μg/L^4.00μg/L范围内线性良好,检出限为0.000 2 mg/L,RSD为2.0%~4.6%,加标回收率为94.0%~108%。The method was established for determination of trace NO2^- -N in the Yangjiaopu source water by enrichment of self-made floatation machine and spectrophotometry. The attention for operation was given. The good linear relations were obtained in range from 0 μg/L to 4.00 μg/L. The detection limit was 0. 000 2 mg/L, RSDs 2.0% -4.6% , recoveries 94.0% - 108% .
