| Abstract: | A method for determination of Pb in cyanide solution by AAS with citric acid as a masking reagent in basic medium was reported.The method has been applied to the determination of Pb in cyanide solutions.The results are in agreement with those determined with other methods. The precision for the sample with w (Pb)=2.19 mg/L is 1.8% RSD( n =10). |
