A simple method using Chelex-100 chelating resin and Atomic Absorbance Spectroscopy determination of lead, cadmium and copper in high-salt food was established. This method could solve the problem of interference on the determination of lead and cadmium in salt matrix. Kd values of sodium (Na), lead (Pb), cadmium (Cd) and copper (Cu) on chelating resin was measured. The influence of pH values of solution on absorption and behavior of ions on resin were investigated. Elution curve for Na and Cd was demonstrated. Absorption capacities of resin to Pb/Cd/Cu/Na were determined. The developed method was applied for analysis of high-salt samples. The recoveries were in the range of 91.6%~98.6% with relative standard deviations (RSDs) in the range of 2.0%~6.7%.
