Abstract

A simple and rapid spectrophotometric method has been found for the determination of nitrate content in natural water according to brucine method by means of neither particular apparatus nor troublesome procedures. Brucine reacted with nitrate in the presence of 30 N sulfuric acid to develop stable color with good reproducibility after 30 minutes reaction at $60^{\circ}C$<\TEX>. An essentially linear relationship to the nitrate concentration was observed in the range of 0.07~0.6 ppm at 410 nm, and it was established that the number of absorbing species in the reaction system was only one between 400 and 490 nm. Among the interferences, nitrite could be removed by the addition of methanol.

特別한 裝置나 複雜한 操作없이 簡單하고 迅速한 brucine 法에 依한 窒酸이온의 吸光光度 定量法을 定하였다. 檢液을 brucine 試液과 30N 黃酸으로 $60^{\circ}C$<\tex>에서 30分間 反應시키면 安定하고 再現性이 좋은 發色을 얻을 수 있으며, 410nm에서 窒酸性窒素의 濃度가 0.07ppm부터 0.6ppm까지 吸光度와 直線的 關係가 있다. 또 反應系에서 吸光綜의 數는 단 하나임을 確認하였다. 妨害이온들중 亞窒酸이온은 메탄올로서 除去할 수 있다.
