PROBLEM TO BE SOLVED: To solve a problem in that there is no heavy metal-treating agent capable of highly treating a heavy metal-contaminated material contaminated especially with an anionic kind among harmful heavy metals in an alkaline region.
SOLUTION: This heavy metal-treating agent comprising tannin, silicate and an iron compound and/or magnesium salt can highly treat the anionic kind heavy metals such as 6-valent chromium, etc., in the alkaline region. Since the heavy metal-treating agent shows a high performance in an alklinity, by simultaneously using a dithiocarbamate of an amine excellent in the heavy metal-treating performance of a cationic kind such as lead, etc., it is possible to treat the anionic kind and cationic kind of the heavy metals at the same time.
