    摘要： The present invention relates to a process for selectively removing molybdenum from a solution which contains molybdenum, said process comprising the following steps: bringing the solution to an acid pH lower than or equal to 3, preferably lower than or equal to 2, even more preferably lower than or equal to 0.5, by the addition of an inorganic acid; adding at least one organic solvent, preferably toluene or xylene, to the solution and stirring continuously so as to create a water-organic emulsion; adding to the water-organic emulsion at least one alkaline metal xanthate having the general formula MeRX, wherein R is a linear or branched alkyl group having a number of carbon atoms higher than or equal to 2, Me is an alkaline metal selected from Li, Na, K, Rb, Cs and Fr, and X is the xanthate group, so as to form a complex with molybdenum wherein the molar ratio molybdenum/alkaline metal xanthate ranges from 1/6 to 1/2, keeping the emulsion at an acid pH by the addition of an inorganic acid, and interrupting the stirring so as to allow the separation of the aqueous phase from the organic phase. The linear or branched alkyl group R preferably has a number of carbon atoms higher than or equal to 2 and lower than or equal to 12. A reductant is optionally added to the starting solution which comprises Mo and V.

    摘要： Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

    摘要： Arsenic is a poisonous metalloid which, because of its hydroscopic nature, is primarily transported through water. Most plant species, including the nopal cactus, produce a sticky substance called mucilage. Mucilage swells in water but is insoluble and can precipitate ions, bacteria and particles from aqueous solutions. The invention includes a method of separating particulates and heavy metals such as arsenic (As) from drinking water using natural flocculants obtained from cactus mucilage. The extraction techniques and the methodology for using the cactus mucilage obtain higher As removal than conventional methods, like aluminum sulfate precipitation.

    摘要： The use of a coupling agent containing a mercapto, disulfide, tretrasulfide and/or polysulfide end group provides a mercury removal media having increased reactivity, stability, and mercury removal ability. The mercury removal media described herein is prepared by reacting an organophilic clay containing onium ions with a mercapto, disulfide, tetrasulfide, and/or polysulfide end moiety. Alternatively, the clay can be made organophilic by onium ion reaction prior to or simultaneously with the coupling reaction of the mercapto- or sulfide- end group-containing coupling agent.
