PROBLEM TO BE SOLVED: To provide a toxic heavy metal trapping material which can quickly and efficiently trap many toxic heavy metals, regardless of their kinds. SOLUTION: The toxic heavy metal trapping material contains R<SB>2</SB>O component (R is an alkali metal), CaO component, and Al<SB>2</SB>O<SB>3</SB>component, and the content of the R<SB>2</SB>O component exceeds 30%. As the toxic heavy metal trapping material has effects, such as enabling quick and efficient trapping of toxic heavy metals, such as molybdenum, chromium, selenium, and arsenic, discarded from chemical industry, electronic industry, medical facilities, and various research facilities, regardless of the kinds of the toxic heavy metals, it is suitable for use in trapping toxic heavy metals in sewage containing various toxic heavy metals.
