| 摘要 |
The present invention relates to an noble metal recovery apparatus by electroanalysis, having multiple centrifugal water channels, wherein the apparatus is capable of remarkably improving noble metal recovery performance, and is compact to reduce the space occupied by the apparatus, and increases conveniences in handling, management and transport. To this end, the noble metal recovery apparatus by electroanalysis of the present invention comprises a negative electrode unit (-) formed of a mesh or a porous plate in a cylindrical shape and including two or more negative electrode members having different radii arranged in a concentric circle; and a positive electrode unit (+) arranged in a concentric circle between the negative electrode members and between the outermost negative electrode member and an inner wall of a casing so as to form partition walls between the negative electrode members and between the outermost negative electrode member and the inner wall of the casing and form centrifugal water channels. The positive electrode unit forms bypass centrifugal water channels between the positive electrode members arranged in a concentric circle.
