| Abstract: | A atomic absorption spectrometry was developed to determine nickel in metallurgical products. The addition of 1920ppm Lanthanum nitrate into sample solution can be eliminated the interferences of copper, iron as well as sulfuric acid and phosphoric acid. The relative error is less than 5% for 30ppm of Ni in sample solution inclnding 0. 6mol/L H_2SO_4 and H_3PO_4 in the presence of 30ppm of copper, iron and 15ppm of cobalt. |
