Abstract: The invention relates to a process for applying electrode layers to a polymer electrolyte membrane strip in a desired pattern, wherein the front and back of the membrane are continuously printed with the electrode layers in the desired pattern using an ink containing an electrocatalyst. The printed electrode layers are dried at elevated temperature immediately after the printing operation, the printing taking place while maintaining accurate positioning of the patterns of the electrode layers on the front and back in relation to one another.

Abstract: The lowering of the nitrite content of aqueous solutions by treatment using hydrogen peroxide in the acidic pH region can be controlled by measuring the redox potential. In contrast to the teaching of the prior art, in the process according to the invention, the addition of the hydrogen peroxide is not terminated in the region of the highest redox potential but only after lowering the potential to a value of 650+/-10 mV. In this manner, nitrite contents below 1 mg/l can be obtained even when the solutions additionally contain varying amounts of various constituents which can be oxidised by H2O2.

Abstract: Aqueous bleaching agent suspensions based on a water-soluble peroxycarboxylic acid suspended in a carrier liquid in the presence of an organic thickening agent and of an acidifying agent exhibit an improved storage resistance over known suspensions with this base. This is achieved by means of pourable to pasty bleaching agent suspensions which contain a xanthan polysaccharide or agar polysaccharide as thickening agent and, in addition, a hydrate-forming neutral salt which desensitizes peroxycarboxylic acids. Preferred suspensions exhibit a pH of 2-5 and contain 10-30% by wt. diperoxydodecanedioic acid, 5-20% by wt. sodium sulfate and 0.1-1.0% by wt. xanthan. The use of non-dried, hydrophilized and optionally in situ desensitized peroxycarboxylic acids is especially preferred. The bleaching agent suspensions are prepared by homogeneously suspending the peroxycarboxylic acid in the thickened carrier liquid. The storage-resistant bleaching agent suspensions are used as laundry bleaching agents and for preparing cleaning agents and disinfection agents.

Abstract: The invention relates to a process for detoxifying cyanide- and/or cyanocomplex-containing aqueous solutions in the presence of heavy metals from the series consisting of Mn, Co, Ni, Cu, Cd, Zn, in particular Cu, by oxidative treatment of the solutions with a peroxide compound at pHs of 8 to 12, the peroxide compound used being an alkali metal percarbonate. The alkali metal percarbonate, preferably 2 Na2CO3 . 3 H2O2, is preferably added in solid form to the solutions to be detoxified. The process according to the invention, with respect to the use of peroxide compound, is significantly more effective than the previously known process using hydrogen peroxide.
