To provide a decontamination method and system for soil and the like for decontaminating soil such as fields and water contaminated with radioactive materials reliably and rapidly on site, performing decontamination with precision, and enhancing the efficiency of decontamination. The invention improves the decontaminated soil by adding a soil activator to the decontaminated soil, and then the improved soil is returned to the original field readily to promote the restart of farming. Further, the invention separates the radioactive materials adhering to or deposited on the soil from the soil precisely and then the radioactive materials are concentrated. The invention enables a reduction in the volume of the contaminated soil and achieves a safe treatment of the radioactive materials. An object to be decontaminated contaminated with radioactive material is introduced into an acid eluting solvent to dissolve the radioactive material. The radioactive material dissolved is concentrated and separated from the eluting solvent in the present method. The object to be decontaminated comprises contaminated soil and contaminated liquid. One or both of the contaminated soil and the contaminated liquid are collected and introduced into the eluting solvent. The radioactive materials and the object to be decontaminated dissolved in the eluting solvent are separated into solid and liquid. The decontaminated soil separated from the eluting solvent is collected. The eluting solvent used for separating the radioactive material and in which radioactive material is dissolved is concentrated.

A method and a system for activating the surface of a parent material suitable for pretreatment in electrochemical treatment, e.g. electroplating, in which productivity can be enhanced while reducing the facility cost by performing degreasing and removal of an oxide film on the surface of the parent material simultaneously, efficiently and rationally using an inexpensive safety solution, and waste liquid can be reused and environmental contamination can be prevented by rationalizing waste liquid treatment. The method for activating the surface of a parent material is used for degreasing and removing an oxide film on the surface of a material to be treated. A solution for removing an oxide film having a specified acidity is prepared by dissolving pressurized carbon dioxide into a specified quantity of water.
