ABSTRACT:
Noxious wastes are detoxicated by admixing a detoxicating agent to noxious wastes containing heavy metals, PCB, or the like and eliminating noxious materials in the wastes, in which the detoxicating agent comprises sodium, potassium, calcium, lithium, barium, magnesium, strontium, cobalt or nickel, copper and zinc contained in an ionic state to a diluted aqueous solution comprising tannin and pyrolignous acid as the main ingredient. Further, the detoxicating agent is admixed together with cement to the noxious wastes containing heavy metals, PCB or the like, thereby eliminating noxious substances in the wastes and solidifying them.
