Abstract (en)

Process for the preparation of a solid carbon-containing material having a sorption capacity for metal ions. <??>The invention concerns a process of preparing solid metal sorbents from cheap carbonaceous material, like rubber waste, peat, coal or petroleum coke. The material is first mixed with sulphur and heated at 120-500 DEG C and then subjected to a treatment with an aqueous alkali solution. <??>Optionally and prior to the latter treatment a moderate oxidizing step is included. The resulting solid product is an excellent metal sorbent for effluent treatment and the like.
