Kurzfassung:
A collaborative study was made of a method for the determination of VC-13 Nemacide residues, based on the alkaline hydrolysis of the pesticide to produce 2,4-dichlorophenol, which is measured colorimetrically with 4-aminoantipyrine and potassium ferricyanide. Results indicate that cleanup technique is critical and not effective for some crops. Several changes in the method were recommended for the next study. Three of five collaborators obtained satisfactory recoveries at levels of 50—250 ppb.
