| Abstract: | A method for the determination of micro amounts of calcium in metal Mg by FAAS with OP as sensitizer was presented in this paper The metal Mg was dissolved with HCl,OP was added as sensitizer and SrCl 2 as releasing agent It was found that the absorbance was increased 50 percent by adding OP,the linear relationship between absorbamce and the concentration of calcium was in the range of 0-1.5mg/L,the detection limit was 0 015mg/L This method was proved to be reliable and convenient |
