Abstract
⺠Hazardous waste was used as a secondary resource for cadmium extraction. ⺠97% of cadmium was extracted in 30 min leaching at 25 °C using 8% (V/V) H2SO4. ⺠The kinetics analysis showed that the dissolution was governed by diffusion control. ⺠Kinetic model was: 1-3(1-α)23+2(1-α)=0.63[H2SO4]1.35(d)-0.238SL-0.76(SS)0.58exp-7.23RTt. ⺠Characterization of sample before and after extraction confirmed kinetics model.
