Heavy metal treatment agent, and method for treating incinerated ash and wastewater using same

Abstract

Provided are: a novel heavy metal treatment agent having improved performance for treating elements of groups 6-16 of the periodic table or compounds thereof, including treatment of incinerated ash and wastewater, etc.; and a method for treating incinerated ash and wastewater using the heavy metal treatment agent. This heavy metal treatment agent includes at least one dithiocarbamate of one or more amine compounds represented by any of formulae (I) to (III): wherein m represents an integer of 3 to 6; wherein each of the n Xs independently represents a hydrogen atom or a 2-aminoethyl group, at least one X is a 2-aminoethyl group, n is an integer of 1 to 3 and the total number of nitrogen atoms is 4 to 8; and wherein o is an integer of 0 to 2, p is 0 or 1, q is 0 or 1, r is an integer of 0 to 3, the sum of o, p and r is greater than or equal to 1, and the total number of nitrogen atoms is 3 to 7.
