摘要： Heavy metals are efficiently removed from contaminated soil by a process which comprises leaching or washing the soil with a mild leachant solution. The leachant solution is comprised of an aqueous solution of an acid and a salt. The anion of the acid forms a water-soluble salt with the heavy metals which contaminate the soil. The salt component is comprised of at least one alkali metal, alkaline earth metal, or an ammonium salt having one or more anions which also form a water-soluble salt with the heavy metals leached from the contaminated soil.

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.

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： The anticorrosive properties of a coating autodeposited on a metal substrate are improved by contacting the autodeposited coating with an aqueous solution containing Group IIA or Group IIB metal cations (e.g., calcium or zinc cations) and phosphate anions prior to curing. The rinse solution is preferably acidic and can be prepared, for example, from calcium nitrate and an oxy acid of phosphorus or zinc dihydrogen phosphate. Optionally, the rinse solution also includes an accelerator such as hydroxylamine.
