20090081103 | Process for the Manufacture of Monobasic Potassium Phosphate - A process for producing monobasic potassium phosphate is provided wherein a reaction mixture of phosphoric acid is combined with potassium hydroxide. The resulting product is cooled to allow crystallization of the product. The product is homogenized and spray dried, resulting in a pure free flowing powder of monobasic potassium phosphate (MKP). | 03-26-2009 |
20100218676 | Method and Composition For Sorbing Toxic Substances - Toxic substances such as heavy metals are extracted from a medium using a sorbent composition.

20100243568 | Method of Sorbing Discolored Organic Compounds from Water - Discolored organic compounds (DOC) may be extracted from a medium using a sorbent composition derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxitic ores. In some aspects, the sorbent composition is slurried with the medium. In other aspects, the sorbent composition is formed into pellets or the like, which are contacted with the medium. The red mud (along with adsorbed contaminants) is then separated from the water using any suitable technique, such as filtration, sedimentation, or centrifugation. | 09-30-2010 |
