HEAVY-METAL ELUTION INHIBITOR

摘要

PROBLEM TO BE SOLVED: To provide a heavy-metal elution inhibitor which inhibits the elution of a heavy metal with small loadings and reduces an amount of an odorous gas such as carbon disulfide when it reacts with the heavy metal. SOLUTION: The heavy metal elution inhibitor contains a dithiocarbamate and urea. A heavy-metal elution-inhibiting method makes the heavy-metal elution inhibitor work on a heavy metal-containing material to reduce the generation of the odorous gas. COPYRIGHT: (C)2009,JPO&INPIT
