| Outline of Final Research Achievements |
The processing of electrowinning and electroplating for less noble metals as Al and Mg are impossible in aqueous solutions. Electrochemical and electrodeposition behaviors were examined in various aprotonic solvents. Metal chrolide solbility to dimethylsulfone bath is Al：more than 40 (mol%)，Zr：20，Mg, Li：10，Nd, La：less than 1, respectiveely.
It was confirmed that Al electrodeposited in dimethylsulfone bath. However, other less noble metals didn't deposit. Extraction of Al from the dimethylsulfone bath containing impurity such as Mg, Li is suggested.
