摘要: A novel heavy metal-binding agent is obtained by reacting a resin containing in its molecular chain --NH--, --NH.sub.2, or both thereof with carbon disulfide and, if necessary, treating the reaction product thus obtained with a base. As compared with conventionally known metal-binding agents, the present metal-binding agent can remove heavy metals more effectively from solutions or gases containing these metals even in a range of extremely low concentrations, and, hence, is useful for pollution control.
