摘要： A method and composition for controlling an exothermic reaction between a powerful oxidizing agent such as the permanganate salts, and reducing agents such as polyhydroxy organic compounds, comprises non-charged, relatively hydrophobic pigments which can be slurried at relatively high solids. The pigment may be calcium carbonate, diatomaceous earth (diatomite), talc, or blends thereof. The pigments are not flocculated in permanganate slurries and can be dispersed at high solids contents. The dispersions can be spray dried or pelletized with controllable moisture contents from about 0.1 to 10%. The resulting composition yields effective control of the exothermic reaction with more uniform and reproducible results.

摘要： Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxitic ores. Exemplary sulfidizing compounds are H 2 S, Na 2 S, K 2 S, (NH 4 ) 2 S, CaS x . The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. The sulfidized red mud is effective for sorbing some contaminants, such as mercury, which are not effectively sorbed by red mud. Conversely, red mud is effective for sorbing other contaminants, such as arsenic, which are not effectively sorbed by sulfidized red mud. Thus, some aspects of the invention utilize combinations of red mud and sulfidized red mud, which potentially can allow for the extraction of a wider range of contaminants.

摘要翻译： 使用吸附剂组合物从介质中提取有毒物质如重金属。 该组合物是通过红泥的硫化衍生而成的，其中含有源自拜耳铝土矿矿石的水合氧化铁。 示例性硫化化合物是H 2 S，Na 2 S，K 2 S，（NH 4）2 S，CaS x。 硫含量通常比红泥中残留硫高约0.2至约10％。 硫化红泥对于吸附一些不被红泥吸收的污染物如汞是有效的。 相反，红泥对于吸收其他不被硫化红泥吸收的其他污染物如砷是有效的。 因此，本发明的一些方面利用红泥和硫化红泥的组合，这可能允许提取更宽范围的污染物。
