METHOD OF DETERMINING HYDROQUINONE AND METOL IN AQUEOUS SOLUTIONS Russian patent published in 2001 - IPC

Abstract RU 2172952 C1

FIELD: analytical methods. SUBSTANCE: sample is preliminarily treated with dioxane at ratio of initial volumes of aqueous and organic phases 10:1 in presence of 35- 39% of ammonium sulfate, after which hydroquinone is determined by voltametric technique in released organic phase and metol is aqueous phase on platinum electrode. Method can be recommended for controlling chemical compounds production. EFFECT: increased sensitivity and expanded application area. 1 tbl
