Japan, Sept. 16 -- SHIMIZU CORP has got intellectual property rights for 'DESIGN METHOD OF ELUTION SUPPRESSION STRUCTURE OF BARIUM ION, METHOD FOR TREATING SELENIUM-CONTAMINATED SOIL.' Other related details are as follows:
Application Number: JP,2022-112531
Category (FI): B09C1/08
Stage: PROBLEM TO BE SOLVED: To provide a method for designing an elution suppression structure of barium ions capable of designing an elution suppression structure of barium according to an amount of selenium-contaminated soil, and a method for treating the selenium-contaminated soil therewith.SOLUTION: A method for designing an elution suppression structure of barium ions comprises: calculating barium ion elution amount Mb of selenium-contaminated soil; calculating barium ion elution amount MB of barium-amended soil; calculating an elution rate X of the barium ions eluted from the barium-amended soil based on a formula (1) from the barium ion elution amount Mb, the barium ion elution amount MB, and an addition amount A of a barium compound with respect to the selenium-contaminated soil; and determining at least one of an amount of a compound containing a negative ion that is bonded with the barium ion eluted from barium-amended soil based on the elution rate X to form a salt of low solubility or a harmless compound, and an amount of an absorbent that absorbs the barium ions eluted from the amended soil.[Formula 1].SELECTED DRAWING: None (Grant)
