수중 암모니아성 질소는 각종 수질오염을 일으키는 물질로서 관리대상이다 . 인도페놀법을 변형한 발색대 길이 측 정으로 암모니아성 질소를 분석하기 위한 기초 실험을 수행하였다. 1-naphthol을 발색제로 사용한 암모니아성 질소 분석에서 최대 흡광도는 720㎚ 부근의 파장대에서 관찰되었고, 적정 주입양은 0.5-1.5㎖였다. 발색 반응은 신속히 진행되어 20분이 경과하여 전체 최고 흡광도의 80%으로 나타내었고, 발색 시약을 조제하는 과정에서 NaOH 농도 는 1.5-2.5M 농도로 설정하였으며, 초기 pH는 영향을 미치지 않았다. 또한, 25℃의 온도에서는 발색대의 길이에 미 치는 영향이 미미한 것으로 나타났다.

Because ammonia in water body can cause water pollution as a result of generating ammonium ion, it is of importance in the management of water quality. This work performed to analyze the ammonium ion by measuring the color band length on the basis of modifying the indophenol method. When 1-naphthol was employed as a coloring agent, the maximum absorbance was shown near 720㎚, where the proper injection was in the range of 0.5-1.5㎖. About 80% of absorbance was observed after the color development was made within the 20 minutes. In the manufacturing of coloring agent, the proper concentration of NaOH was 1.5-2.5M, and the effect of pH on the color development is negligible. In addition, the color development was effectively in the region of room temperature.
