Предложен новый способ фотометрического определения 1 - метил - 1, 2 - дициклопропилциклопропана в почвах и в растительных материалах. Анализируемую пробу обрабатывают этиловым спиртом или водно - спиртовой смесью в определенном соотношении. После перемешивания, выдержки и нагревания через анализируемую пробу и серную кислоту барбатируют воздух, затем в концентрированную серную кислоту добавляют раствор пара - диметиламинобензальдегида в водном растворе соляной кислоты и этиловый спирт, после чего измеряют оптическую плотность.A new method for the photometric determination of 1 - methyl - 1, 2 - dicyclopropylcyclopropane in soils and in plant materials is proposed. The analyzed sample is treated with ethyl alcohol or water - alcohol mixture in a certain ratio. After stirring, holding and heating, the air is bubbled through the sample and sulfuric acid, then a solution of para - dimethylaminobenzaldehyde in an aqueous solution of hydrochloric acid and ethyl alcohol is added to concentrated sulfuric acid, and then the optical density is measured.
