| Abstract: | The determination method of manganese in anode active materials of waste Zn-Mn batteries using HCL-H2O2 fusion method heated by microware oven was briefly described manganese will be dissolved in solvent.Then suitable conditions were HCl-2mol/L; H2O2-3%; heated time-60s; microwares efficiency-20%; liquid:solid-0.2:12ml. The measuring the content of manganese whit 724-visible spectrophotometers. |
