Сера техническая. Определение общего содержания углерода. Титриметрический метод
Название (англ.):
Sulphur for industrial use; Determination of total carbon content; Titrimetric method
Описание (англ.):
Gives the potentiometric and visual methods als alternatives for the final titration. The principle consists in the combustion of the sulphur in a current of oxygen. Oxidation and fixation of the sulphur dioxide and trioxide gases in chromic and sulphuric acid solutions. Absorption of the carbon dioxide formed in a solution of barium hydroxide, followed by titration in the presence of phenolphthalein and screened methylorange (by xylene cyanol FF) asindicator. Has also been approved by the IUPAC.
