Abstract: The invention relates to a method for preparing amorphous molybdenum oxide adsorption material and an application thereof. The invention aims to solve the technical problem of low recovery efficiency of silver ions in coexisting silver-containing wastewater in the prior art. The method of the present invention includes:1) preparation of electrolyte; and 2) subjecting to cyclic voltammetry. The amorphous molybdenum oxide adsorption material prepared by the present invention is used as an adsorbent for adsorbing and reducing silver ions in wastewater. The invention successfully prepares amorphous molybdenum oxide (MoOx) by cyclic voltammetry, which has a highly selective reduction adsorption for Ag+. Silver ions and the adsorbent MoOx could be subjected to redox reaction to remove silver ions in water. The removal efficiency of the silver ions in wastewater by the amorphous molybdenum oxide prepared by cyclic voltammetry of the invention is up to 99.85%.

Abstract: An iron composition having a plurality of elemental components is disclosed. The major component is an iron component of at least about 68% to about 92% iron by weight. Other components by weight include manganese; cerium; carbon; phosphorous; sulfur; aluminum; silicon; chromium; copper; and zinc. Combined with layers of sand, brick chips and/or charcoal, the iron composition can be used to create a water filter for filtering inorganic arsenic species and soluble metal ions out of water. To enhance hydrous ferric oxide complexation and precipitation, the iron composition may be treated with food grade acids or a water mixture.

Abstract: A filter for removing contaminants from air. The filter includes (a) a substrate that does not have any volatile ammonia on the surface thereof; (b) copper that has been impregnated onto the substrate; and (c) molybdenum and/or tungsten that has been impregnated onto the substrate. The filter can be made using an aqueous solution(s) that contains one or more of a first copper salt and a second salt that include a polynuclear anion that contains molybdenum, tungsten, or both. Because the metals can be impregnated onto the substrate surface without using an ammonium-based solution, the need to manage ammonia off-gassing is avoided. Further, no volatile ammonia would be present on the resulting substrate surface.
