| Abstract: | The EDTA method for determination of alkali in FCMP is modified,which includes using no KCN,decreasing the amount of solution aspiration to 5mL,introducing correction factor. The results show that precision and accuracy are good,absolute error is below 0.25% comparing with the national standard, and RSD<0.24%. |
