摘要： The application relates to a process for removing nobler metal ions than iron, especially copper ions, from acidic process and waste waters by reduction under an inert gas atmosphere with carbonyl iron powders which have previously been subjected to a thermal treatment with hydrogen to remove nitrides and carbides. This process results in residual metal ion content

摘要： Pigment formulations and their use.The formulations contain pigments, organic solvents and from 10 to 80% by weight of a wetting agent consisting of a non-ionic organic compound which has a viscosity of from 500 to 10,000 mPa.s and has been produced by reacting an alkylated amide/formaldehyde reaction product and an epoxy resin, which may or may not be modified, in a weight ratio of from 9:1 to 1:9. They are used as additives in surface-coating binders, especially in cationic electrocoating finishes.
