“…У періодичній науковій літературі для визначання БАХ пропонують спектрофотометричний метод у різних його варіаціях -пряма [9 -11], похідна [12], диференційна [13,14] спектрофотометрія та метод екстракційноспектрофотометричного визначення [15,16]. Також знайшли застосування методики з використанням методів високоефективної рідинної (ВЕРХ) [17 -20], тонкошарової (ТШХ) [21] та газової (ГХ) [22] хроматографії, хромато-мас-спектрометрії [23], капілярного електрофорезу [24], потенціометричного титрування з використанням іон-селективних електродів [25].…”
