Determination of 2-Isopropoxyphenyl Methyl Carbamate-Propoxurin Roach Control Peanut Butter by High Performance LiquidChromatography

摘要

A method for the determination of 2-isopropoxyphenyl methylcarbamate, also known as Propoxur, in pesticides was developed for liquid chromatography equipped with a UV detector. Roach peanut butter sample was prepared with soxhlet extraction ten times; the standard solutions were prepared with n-butyrophenone and methanol as an internal standard, and both isopropoxyphenol (IPP) and 2-isopropoxyphenyl methylcarbamate (propoxur) as control standards. The target compound propoxur was well-separated and showed no interferences in the chromatograms. Propoxur was determined to comprise less than 2% of the sample.
