Gives a titrimetric method for the determination of the total and alkali soluble calcium and magnesium contents of crude sodium borates for industrial use. Procedures are described for special cases for determination of total calcium to eliminate interference by silica, iron or aluminium. Also applicable to products in which the calcium content, expressed as calcium, is not lower than 0,01% (m/m) and not greater than 1,0% (m/m), and in which the magnesium content, expressed as magnesium, is not lower than 0,01% (m/m) and not greater than 0,2% (m/m). Includes sections on references, principle and reagents.
