| titleOfInvention | Method for measuring copper smelting smoke indium |
| abstract | The invention provides a method for measuring copper smelting smoke indium, wherein the method has the advantages of simplicity and fastness in operation, exact measuring result and low cost and belongs to the technical field of chemical detection. The technical points are as follows: the method comprises the following steps of: 1) preparing a 0.1mg/ml standard indium solution containing indium; 2) measuring a sample: putting 0.2-1.0 g of sample in a beaker, adding 9 ml of analytical pure hydrochloric acid (HCl) and 3 ml of analytical pure nitric acid, heating to dissolve and evaporate nearly dry, and adding 3 ml of HCl(1+1) and 1 ml of H2SO4(1+1), heating to dissolve, transferring the solution into a 50 ml volumetric flask after the solution is cooled, diluting the solution to a scale by using water, and shaking up; after the solution is classified or filtered, spraying and measuring at wavelength 303.9 by an atomic absorption spectrometer; 3) drawing a working curve; and 4) calculating. |
