The analysis of Calcium in high-pure magnesia is very important for the development of iron and steel industry. Here, describes a method and detail conditions on determination of calcium in high-pure magnesia with CPAmN after separating calcium with calcium sulfate. The molar absorptivity and Sandell sensitivity of calcium with CPAmN are 1.0 × 10~4l·mol~(-1)·cm~(-1) and 0.0041μg Ca·cm~(-2) under the experimental conditions. Beer's law is obeyed for 0-50μg of calcium in 25 ml of measuring flask. The coefficient...

The releasing agent, deionizing agent and protecting agem for determination of calcium have been investigated. The interferences were studied, and the optimun conditions were found experimentally. A method for determination of calcium in aluminium-silicon alloys by N_2C C_2H_2 flame atomic absorption has been described. The procedure is characterized by simplicity, rapidity and sensitivity without preliminary separation. The results are consistent with these by atomic fluorescence spectromettry etc.
