METHOD OF CONTROLLING MAIN COMPONENTS OF CHLOROALUMINATE MELT Russian patent published in 2015 - IPC G01N27/26 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of analytical chemistry and can be used for automatic or express-analysis in laboratory or industrial conditions. The method of controlling main components of a chloroaluminate melt includes the determination of the molar ratio of the said components in the liquid chloroaluminate melt by a potentiometric method; measurement of the potential difference is carried out between a working electrode of aluminium and an aluminium comparison electrode both located in an electrolyte , with the comparison electrode being separated by a diaphragm from the main melt and representing an assembly from a ceramic casing and aluminium wire, submerged into the located in a casing chloroaluminate melt, saturated by solid potassium chloride, with the molar ratio of the main components in the melt being determined by the value of difference of potentials between the electrodes by means of preliminarily built calibration curves in coordinates "difference of potentials - ratio of concentrations of potassium chloride to aluminium chloride".

EFFECT: compactness of the installation, cheapness of the applied material and simplicity of technological equipment, applied for the said method realisation.
