    摘要： The present invention relates to an aqueous alkaline composition (A) for alkaline passivation of metallic components comprising at least in part surfaces of zinc or zinc alloys, containing iron(III) ions, phosphate ions, and one or more complexing agents, where a free alkalinity ranges from 1 to 6 points, and the pH is at least 11. The aqueous compositions (A) can additionally contain nonionic surfactants, so that such compositions are suitable for use in a method in which both cleaning and alkaline passivation of the metallic component occur in one step. The present invention further relates to a method for alkaline passivation of metallic components by contacting them with composition (A), and further a method for surface treatment in automobile body production, in which the alkaline passivation step using composition (A) is followed by an acid passivation step using a composition (B).

    摘要： Many prior art processes for cleaning predominantly organic hard surfaces have been found to be considerably less effective in removing very fine particles on such surfaces than are the best cleaners for metallic surfaces. However, it has been found, and forms the basis of this invention, that fine particles can be removed effectively from organic surfaces by an indirect process of first forming a thin solid coating over the surface and then removing the solid coating, into which the fine particles that formerly contaminated the surface to be cleaned have presumably become incorporated. Substantially hydrolyzed poly(vinyl acetate) has been found particularly useful for forming the thin solid coating when this coating is to be removed by treatment with an acidic aqueous solution; acrylate polymers are preferred if the solid coating is to be removed by an alkaline aqueous solution. In either instance, in order to obtain good wetting without damaging the surface to be cleaned, the material that forms the bulk of the solid coating is preferably applied to the surface to be cleaned in an aqueous solution or dispersion that also contains surfactant molecules that include imidazoline moieties. A method of quantifying the degree of removal of solid particles is also provided.

    摘要： The invention is a process and an apparatus for removing metal contamination from soil. In the method, the soil is treated to produce soil with a small particle size. The particulate soil is then separated into a coarse fraction and a fine fraction. The coarse fraction and the fine fraction are contacted with a leach solution in separate contacting zones to remove the metal contamination from the soil, the metal is removed from the leach solution and the leach solution recycled to the leaching zones.
