Separation method using Chelex-100 chelating resin and GFAAS determination of copper in seawater for culture was eatablished. This method could solve the problem of interference on the determination of copper from sodium chloride matrix. Kd value of Na and Cu on chelating resin was detected. The influence of pH value of solution on adsorption and behavior of ion on resin were analyzed. Elution curve for Na and Cu was drawn. Adsorption capacity of resin was detected. Recovery of method:94%-102%, RSD:1.5%-4.2%.
