| Abstract: | A new indirect atomic absorption spectrometry (AAS) method for determination of trace chlorine in high-purity water of power plants is established. After precipitation of AgCl,the surplus of Ag~+ in the solution is determined for chlorine content calculation. RSD of the method is 2.3%~8.6%, the rate of recovery is 94%~103%, and the sensitivity is 0.029 mg/L (1% A). |
