| Abstract: | The methods for leaching heavy metals from electroplating sludge were investigated and compared.Finally,H_2SO_4 was selected as the leaching agent,and the optimal leaching conditions were also determined:particle size100 meshes,every (2 g) of sludge is dissolved in 10 mL,pH value 1.5 of sulfuric acid solution,and oscillating time is 1.5 h under normal temperature.Under these conditions,maximum leaching rate of Cu,Ni,Zn and Cr can be obtained,which can reach more than 95 % for each of them,laying a better fo... |
