摘要： An electrolyte containing 65 g/l zinc and 150 g/l Cu is purified in zinc, that is, the copper is removed, by causing the electrolyte to fluidize a bed 8 of 1/2 mm copper particles. The bed is fluidized by 25% to make it 42 cm deep. An anode 11 is disposed above the top of the bed. A cathode 9 is disposed part-way up the bed. Copper is electroplated onto the bed particles. Any zinc which may be electroplated onto the bed particles tends to redissolve with concomitant cementation, on the particles, of copper, which can be recovered. The electrolyte is thus eventually completely stripped of copper and can be used for zinc electrowinning.By controlling the pH of the electrolyte, substantially one metal, or one desired combination of metals, may be removed. In particular, pure copper deposition can be completed at low pH even in the presence of cadmium; upon a substantial increase in pH, cadmium deposition will occur.
摘要翻译：在锌中纯化含有65g / l锌和150g / l Cu的电解质，即通过使电解液使1/2的铜颗粒床8流化，除去铜。床层流动25％，使其达到42厘米深。阳极11设置在床的顶部上方。阴极9被布置在床的一部分上。将铜电镀到床颗粒上。任何可能电镀在床颗粒上的锌，往往会随着附着的胶结而重新溶解在可以回收的铜颗粒上。因此，电解质最终完全被铜剥离，并可用于锌电解提取。通过控制电解质的pH，可以除去基本上一种金属或一种所需的金属组合。特别是即使在镉存在下，也可以在低pH下完成纯铜沉积; 在pH的显着增加时，将发生镉沉积。

摘要： A method of carrying out an electrochemical reaction comprises setting up a fluidized bed of particles at least some of which have at least their surfaces conducting or semi-conducting, using upwardly flowing liquid electrolyte, with or without reactant liquid, for the purpose, and applying a voltage gradient across at least a portion of said fluidized bed of particles, the size of particles, the conductivity of and rate of flow of the said electrolyte and/or reactant liquid and the voltage gradient being such that not only are anodic and cathodic faces established in respect of each of some of the at least partly conducting particles but the electropotentials on said faces on substantially each bipolar particle are such that said electrochemical reaction takes place on at least some of said bipolar particles but only on one portion of the surfaces thereon of said particles. The said bipolar particles which, preferably, are spherical or cylindrical may comprise solid conducting or semi-conducting material or cores of non-conducting material with coatings of conducting or non-conducting material thereon.The said method may be, for example, the electrolysis of sea water for the production of hypochlorite or of bromide solution for the production of hypobromite or the decarboxylation of monomethyl adipate to dimethyl sebacate.

摘要： The invention relates to electrochemical cells whereof one electrode is of a particulate type which may comprise a fluidized bed electrode, a packed bed electrode or a circulating bed electrode, an electrolyte being passed through the particulate electrode possibly for fluidizing and/or circulating the particles of the electrode. Whereas in previous cells of this kind a diaphragm has been arranged between the particulate electrode and the counterelectrode of the cell, it has been discovered that such a cell can be operated with the counterelectrode actually in contact with particles of the particulate electrode provided the material of the surface of the counterelectrode is suitably chosen. Among the materials mentioned are graphite, ruthenium oxide, lead oxide and iron oxide.

摘要： An electrochemical cell comprises a housing (1,2) divided by a perforated generally horizontal plate (3) into an upper chamber (4) and a lower chamber (5). Bipolar electrodes (19, 21) are disposed in the upper chamber (4) above perforations (23) in the plate (3), between electrolyte inlet and outlet weirs (11, 13) for flowing electrolyte over the plate (3). The lower chamber (5) is a gas-supply chamber for passing a gas, e.g. propylene, up through the perforations (23), so as to bubble the gas through electrolyte (e.g. NaBr solution) on the plate (3) and into the upper gas-collection chamber (4). A reactor may be formed by stacking several cells with their electrolyte flows in cascade. The cell is particularly suitable for electro-organic syntheses involving a gaseous reactant.
