After pretreatment of soil samples, the experiment used D'rPA(diethyl DTPA) to extract the copper-effective, and in the best condition of determination, used the standard curve method to complete the determination of copper-effective in soil by AAS. The method was simple, linear range, the results of high precision, accuracy, and could meet effectively the needs of the determination of copper in soil samples.
