ABSTRACT:
A toxic waste fixant for detoxification of a contaminated material includes a mixture of ferric sulfate, manganese sulfate, organophilic clays, an oxidizer and aluminium sulfate. The respective amounts are preferably about 15-19% b.w. of ferric sulfate, about 15-19% b.w. of manganese sulfate, about 37-46% b.w. of organophilic clay, about 16-19% b.w. of an oxidizer and about 0-12,5% b.w. of alumimium sulfate. All or part of the ingredients in said fixant may be added as a pretreatment into contaminated materials such as soils, sediments, or sludges. This pretreatment can range from 0 to 100% b.w. to said material. The fixant is blended with various amounts of Portland cement, and/or blast furnace slag, or lime, or gypsum, or coal fly ash, or cement kiln dust as a means to derive a chemical fixation treatment for contaminated soils, sediments, and sludges to prevent the leaching of organic and inorganic compounds and elements.
