Flow Injection On-Line Separation and Preconcentration for the AAS Determination of Micro Amount of Lead in Nickel Sulfate Electrolyte |
| |
| Abstract: | Methods for the separation and preconcentration of micro amount of lead were investigated.A micro column was adapted in flow injection system for on line separation and preconcentration followed by AAS determination of lead in nickel sufate electrolyte.The detection limit of the method was 0.03mg/L,and the relative standard deviation was 3.4% when a sample containing 1.33mg/L lead was determined. |
