    • PROBLEM TO BE SOLVED: To solve such a problem that a conventional solid heavy metal processing agent includes a large quantity of filler (carrier) other than a chelating agent and has only low heavy metal processing ability.
      SOLUTION: The heavy metal processing agent containing piperazine-N,N'-biscarbodithioic acid sodium hexahydrate shows no variation of weight (the content of its effective component) caused by influence of moisture in the atmosphere, and no consolidation of crystalline particles and consequently has excellent economical efficiency in transportation and excellent storage stability. In addition, efficient heavy metal processing is feasible because no generation of a harmful gas (hydrogen sulfide or carbon disulfide) takes place in storage and in use (direct mixing with a heavy metal containing substance), and furthermore the heavy metal processing agent selectively forms an insoluble complex with harmful lead.
