光化学动力学分析法测定 N O3-
Determination of NO - 3 by photochemical kinetic analysis with Congo Red
【摘要】 研究了刚果红溶液的光化学性质, 利用 N O-3 对刚果红溶液在紫外光作用下发生的褪色反应的催化作用, 建立了测定痕量 N O-3 的新方法, 其线性范围为0 ~08 mg/ L。对自来水样品进行加入回收实验, 相对标准偏差在25 % 以下, 回收率在990 % ~994 % 之间
【Abstract】 The photochemical property of Congo Red was studied and an analysis method for determining the trace amount of NO - 3 was developed based on the photochemical reaction of Congo Red with UV radiation The linear range was 0~0 8 μg·mL -1 RSD was less than 2 48%. The recovery was up to 99 4% in the standard addition analysis of tap water
