Determination of Microquantities of Nicotine
니코틴의 미량 정량법
Abstract
A flew spectroscopic method was developed to determine microquantities of nicotine with cyanogen chloride and pyrazolon. Absorption maximum of tile derivative solution appeared at 520nm. The color formed in the proposed method was stable for at least 30 min. at pH 7.5, and followed the Lambert-Beer's law between tile limits of 1 and 5 micrograms of nicotine. The relative errors in burley and flue-cured tobacco leaves were
