Restoration agent for lowering cadmium/lead effective state content in soil, and use method and application thereof

The invention discloses a restoration agent for lowering cadmium / lead effective state content in soil, which is composed of quicklime, calcium sulfate, wood charcoal, iron chloride and water, wherein the weight ratio of the quicklime, calcium sulfate, wood charcoal and iron chloride is (1-2):(1-2):(1-2):(0.5-1), and the water accounts for 30-45 wt% of the soil. The restoration agent can be used for treating heavily polluted soil; and common chemical passivators can only restore lightly polluted soil, and do not have obvious effect on heavy pollution. The restoration agent can be used for treating both acidic soil and neutral soil. The restoration agent has high remediation efficiency for cadmium polluted soil; the reaction mechanisms relate to chemical precipitation and physical adsorption; and when one action fails due to change of the outside conditions, the other action can perform the guarantee function. The restoration agent has certain control actions on the lead effective state content in the polluted soil.

Loading method and application of a metal surface corrosion inhibitor

The invention discloses a loading method and application of a metal surface corrosion inhibitor. The loading method comprises the following steps of: depositing a layer of inert and porous nano oxide film on a metal matrix; performing saturation adsorption of a corrosion inhibitor through impregnation; and covering a protective layer on the surface. The nano oxide film is prepared by depositing an aqueous solution of precursor such as SiO2, TiO2 or ZrO2 on the metal surface through an electro-deposition method. The corrosion inhibitor adsorbed on the nano oxide film is determined by the type of the metal matrix. The protective layer for covering can be a common organic silane film, an inorganic / organic hybridized silane film or a common organic coating. The loading method for the metal surface corrosion inhibitor is used for protecting metals. A preparation process is simple, and the cost is low. When the matrix is corroded, the nano oxide film can release the corrosion inhibitor to protect the matrix; and compared with a mode that the corrosion inhibitor is directly absorbed on the surface of the metal matrix, the nano oxide layer can load more corrosion inhibitor to better protect the metal matrix.
