| Abstract: | A new method has been developed for chemical phase analysis of calcium and magnesium.After choosing selective solvents and optimizing operations, sulphate, oxide and the other phases of calcium and magnesium in the same sample can be determined. After phase separation,ammonium benzoate/cupron were added as precipitation/separation agents, and then determination was conducted by means of complexometry. The determination of three phases of calcium and magnesium is in sequence for one sample with with featues of rapidity,high accuracy and practicability. Application results are satitfactory. |
