摘要： An improved method for the recovery of lead from exhausted lead-acid storage batteries, comprising removal from the storage battery of the sulphuric acid solution, the coating element, the separators between the electrodes and the metal part i.e. grids, connectors and poles and milling of the remaining electrode paste of the storage battery to obtain an extremely fine powder (pastel),characterised by the following operations:a) treatment of the resulting powder with an aqueous saline solution, with a pH of between 0 and 8, capable of solubilising Pb (II) sulphate and oxide, leaving Pb (IV) oxide unsolubilised;b) reduction to metal lead of the bivalent lead ion, present in the soluble fraction, using metal iron, preferably in slight excess with respect to the stoichiometric proportions;c) reduction of the tetravalent lead oxide; andd) recovery of the salts used in the process step a) by elimination of the iron sulphate that has formed. FIG. 1 is a block diagram showing an embodiment of the present method for recovery of lead from exhausted lead acid storage batteries.

摘要： A porous separator, to be used in electrolyzers for producing hydrogen and oxygen by water electrolysis, consists of a fabric or felt entirely made of polyphenylene sulfide (PPS). In order to reduce the voltage drop caused by the separator, the PPS polymeric chain can be made ionically active by the presence thereon of polar groups, such as sulfonic, carboxylic or phosphonic groups.The method for producing the separator comprises the preparation, according to conventional weaving or felt manufacturing techniques, of a fabric or felt entirely made of PPS and the subsequent functionalization for introducing polar groups in the polymeric chain. The functionalization can be carried out either on the starting material, such as PPS polymer powder or flakes, or in any other step of the production of fabric or felt.
