Analysis of cymoxanil fungicide by infrared spectrophotometry

Authorship SCIMAGO INSTITUTIONS RANKINGS

This paper deals with cymoxanil fungicide analysis by infrared spectrophotometry. Liquid and chromatographic methods for cymoxanil determination are known. For quantitative purposes the 9.25gm absorption was considered and this is due to two secondary amine groups -NH-. The method is accurate, precise and specific if the total spectrum is from 2,5 to 15gm.
