Determination of residual p-chlorophenyl p-chlorobenzenesulfonate in orange pulp

, : Determination of residual p-chlorophenyl p-chlorobenzenesulfonate in orange pulp. Jour Agric And Food Chem 5(1): 42-44

A new method for determination of the acaricide, Ovex, in orange pulp involves hydrolysis of Ovex to p-chlorophenol and sodium benzene sulfonate. The p-chlorophenol, recovered by steam distillation, is nitrosated, chromatographed, and measured colori-metrically. This procedure eliminates the phenolic-like impurities, making it possible to determine less than 52 of Oves with a recovery of at least 90%.
