Abstract: An improved electrolytic reactor is provided with a sealed enclosure subdivided into separate solution chambers for an anolyte and for a catholyte by the interposition of an electrically insulating septum with a microporous matrix. The microporous membrane, or septum, permits the controlled passage of ionic species but prevents the gross intermixing of the separate electrolytes in respective contact with the cathode and the anode of the reactor. At least one of the chambers defined on either face of the microporous septum is filled with electrically conductive particulate material--stainless steel balls in one embodiment--acting as extensions of the electrode in that chamber, so as to increase the electrically charged, stable surface available for electrolytic mass transfer. The polarity of the electrodes in the reactor is readily reversible to permit complex processes, such as the recovery of very dilute solutions of metallic ions by first depositing them on an extended-surface cathode and, afterwards, deplating them into suitable recovery solution. The flow passages through the solution chambers are so defined, either by dimensional control or by packing the chamber with static conductive material, so as to ensure turbulent flow of the electrolytes through at least one active chamber in the reactor. Reactors embodying the teachings of the invention may be cylindrical or polygonal, and may contain auxiliary electrodes for use during polarity-reversed operation.The electrolytic reactor is particularly useful, but not limited to the continuous removal of relatively small concentrations of metal ions from large quantities of solutions.

Abstract: A method for the recycle treatment of nickel plating waste water, in order to efficiently recover the nickel components from waste water which has been used for the washing of nickel plated products in a form re-usable as a nickel plating solution as such, wherein the nickel plating waste water is mixed with an aqueous alkaline component so as to remove, by precipitation in the form of hydroxides, contaminating metal ions other than nickel; the filtrate so obtained is treated through an ion exchange process so as to obtain an aqueous solution of nickel salts containing excess free sulfuric acid, a portion of which is then treated with alkali so as to precipitate nickel hydroxide which is separated in the form of nickel hydroxide through filtration by means of a centrifuge; the nickel hydroxide so obtained is then added to the rest of the aqueous nickel salt solution for neutralization with the free sulfuric acid contained therein to form nickel sulfate; and the free sulfuric acid is then removed so as to obtain a highly concentrated nickel sulfate solution.

The apparatus includes: an electroplating solution container, a target, an absorbent piece, and a power supply. All the electroplating solution, workpiece, absorbent piece, and target are placed inside the electroplating solution container with at least partial portions of each workpiece, absorbent piece and target submerged in the electroplating solution. The positive electrode of the power supply is electrically connected to the target while its negative electrode is electrically connected to the workpiece and absorbent piece simultaneously. When the power supply imposes a current through the circuit, the target releases metal ions into the electroplating solution and metal ions reduce and a metal coating is formed on the workpiece. In the meantime, carbocations in the electroplating solution are adsorbed on the absorbent piece.

Abstract: A method for recovery of metal and cyanide from plating baths and rinse waters includes formation of hydrogen cyanide by acid treatment of such solutions, followed by HCN removal through diffusion across a microporous membrane. The method is applicable in a system wherein soluable metal cyanides and metal cyanide complexes are concentrated through use of a basic anion exchange system. Free hydrogen cyanide is released from the anion exchange system by means of an acid regenerant. In a preferred application of the invention, HCN, once having diffused through the microporous membrane, is neutralized with sodium hydroxide, to form a sodium cyanide solution that can be returned to a plating bath.

Abstract: A method and apparatus for selectively recovering ions from an aqueous solution and producing deionized water for reuse. When used in a nickel plating process, a rinse water stream is passed through a first cation removing assembly that contains an ion exchange media having a greater affinity for nickel ions than for most or all other ions present in the system. Rinse water processed by the first cation removing assembly is conveyed to a second cation removing assembly and then to an anion removing assembly so that deionized water is produced and is then returned to a rinse bath. Rinse water is passed through the first ion exchange media until substantially all of the ion exchange sites hold a nickel ion. The other cations in the rinse water are captured by the second cation assembly. The first cation assembly is regenerated using a regeneration solution compatible with the plating bath. The regeneration solution after passing through the first cation assembly releases the captured metal ions and the regeneration solution along with the plating ions is returned to the plating bath.
