To treat waste containing harmful metals such as lead, cadmium, mercury, chromium, copper, nickel, zinc, etc., the waste is mixed with a treating agent containing, as the essential constituent component, solid acid(s) and/or cement and additionally a caking inhibitor, kneaded with water where necessary, then solidified by curing. Harmful metals are thereby stabilized in the thus-solidified cakes and are not released therefrom.

Method for treating wastes

To treat waste containing harmful netals such as lead, cadmium, mercury, chromium, copper, nickel, zinc, etc., the waste is mixed with a treating agent containing, as the essential constituent component, solid acid(s) and/or cement and additionally a caking inhibitor, kneaded with water where necessary, then solidified by curing. Harmful metals are thereby stabilized in the thus-solidified cakes and are not released therefrom.

Waste-treating agent

A waste-treating material which comprises cement and at least one reducing metal, effective for stabilizing industrial wastes containing harmful metals like a heavy metal and the like and cyanides. A preferred example of the reducing metal is iron. Additionally the waste-treating material may also contain at least one member selected from a group consisting of a reducing agent, aluminum sulfate, allophane, and bentonite as the auxiliary. The use of this waste-treating material makes it possible to stabilize the hazardous heavy material and the cyanides contained in the industrial wastes, thereby remarkably contributing to a stabilizing treatment of the industrial wastes.

Waste-treating material

An adsorbent for an autoantibody or immune complex produced by combining an autoantibody with its homologous antigen, which comprises a water-insoluble porous material and a compound having an anionic functional group immobilized onto said material, an apparatus for removing an autoantibody or immune complex thereof using the above-mentioned adsorbent and a method for removing an autoantibody or immune complex thereof from body fluid by passing body fluid through the above-mentioned removing apparatus. According to the present invention, the autoantibody or immune complex thereof can be selectively removed from body fluid without removing useful components in body fluid.
