Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the safety or the like of operation of an analysis method of dithiocarbamate-based agricultural chemicals by a conventional carbon disulfide method without reducing the analysis accuracy. SOLUTION: In this analysis method of dithiocarbamate-based agricultural chemicals in a sample, the sample is made to react with hydrochloric acid under presence of chlorination tin (II), generated carbon disulfide is collected and analyzed, thereby analyzing them. The sample of 1-5 g (amount of solid component) and chlorination tin (II) of 0.5-4 g (dihydrate conversion) are added into a reaction vessel, and then hydrochloric acid aqueous solution of 15-30°C is added. They are boiled, the generated carbon disulfide is collected into a collection tube and analyzed. COPYRIGHT: (C)2008,JPO&INPIT
