ГОСТ Р 50688-94

Soils. Determination of mobile compounds of boron by Berger and Truog method modified by CINAO

Почвы. Определение подвижных соединений бора по методу Бергера и Труога в модификации ЦИНАО

Status: Effective - Introduced for the first time

This standard establishes a method for the determination of mobile boron compounds in soils. The method is based on the extraction of mobile boron compounds from the soil with hot water containing magnesium sulphate, and the subsequent determination of boron by photometric method with hypalizarin or azomethin Ash

Настоящий стандарт устанавливает метод определения подвижных соединений бора в почвах. Метод основан на извлечении подвижных соединений бора из почвы горячей водой, содержащей сернокислый магний, и последующем определении бора фотометрическим методом с хипализарином или азометином Аш
