摘要： The nanocomposite membrane includes a composite of carbon nanotubes coated or chemically bonded with metal oxide nanoparticles. This composite is embedded within a polymeric matrix via interfacial polymerization on a polysulfone support. The metal oxide particles are selected to exhibit catalytic activity when filtering pollutants from water in a water treatment system, or for separating a gas from a liquid, or for selectively separating particles or ions from solution for reverse osmosis (e.g., for desalination systems), or other filtration requirements. A method of fabricating the nanocomposite membrane is also included herein.

摘要： The plate reactor includes a rotatable plate coated with a thin film containing an active photocatalytic nanocomposite. In use, the plate is partially submerged in polluted water so that a portion thereof is exposed to air and light. The exposed areas of the plate gains oxygen from the air, which reacts with the photo-promoted electrons from the coating. This results in the formation of very reactive superoxide radical ions (O2−) and/or the generation of hydroxyl radicals (.OH), either of which can oxidize targeted organic matter and pollutants in wastewater when the exposed area is submerged during rotation of the plate, thus purifying the water. A plurality of paddles radially extend from the edge of the plate to mix the water during rotation.

摘要： The method for detection of cyanide in water is a method for the detection of a highly toxic pollutant, cyanide, in water using ZnO2 nanoparticles synthesized locally by an elegant Pulsed Laser Ablation technique. ZnO2 nanoparticles having a median size of 4 nm are synthesized from pure zinc metal target under UV laser irradiation in a 1-10% H2O2 environment in deionized water. The synthesized ZnO2 nanoparticles are suspended in dimethyl formamide in the presence of Nafion, and then ultrasonicated to create a homogenous suspension, which is used to prepare a thin film of ZnO2 nanoparticles on a metal electrode. The electrode is used for cyanide detection.
