چکیده
|
Keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis (2-diethylhexyl) phosphoric acid (dehpa) and 2-thenoyltrifluoroacetone (htta), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable ni-cd batteries.the conditions for leaching of metal contents in solid materials of the batteries were optimized.the effect of parameters influencing the process for achieving to an efficient and selective extraction of cd, co and ni ions from synthetic samples and leach liquor of spent ni-cd batteries was investigated
