摘要： Semiconductor-Oxides Nanotubes-Based Composite Particles Useful for Dye-Removal and Process Thereof, has been described in this invention, which relates to an innovative method, involving an ion-exchange mechanism operating under the dark-condition in an aqueous solution, for the processing of innovative products consisting of the nanotubes of semiconductor-oxides deposited on (or anchored to or attached to) the surface of flyash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles find potential application in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via the surface-adsorption process, involving the ion-exchange and electrostatic-attraction mechanisms, operating in the dark-condition. The novel composite particles can be recycled for the next-cycle of dye-adsorption by decomposing the previously adsorbed-dye on their surfaces via an innovative approach involving the use of either noble-metal-deposited photocatalyst or a magnetically separable magnetic photocatalyst and an exposure to the ultraviolet (UV) or solar-radiation.

摘要： An electrolytic process and apparatus are disclosed for water purification and pH adjustment. The electrolytic reactor includes an anode, cathode and a bed of particulate ion exchange material modified by converting a portion of the transfer sites to semiconductor junctions. The ion exchange material may be a monobed of either modified anion exchange material or modified cation exchange material, or a mixed bed of both. Undesirable ions are exchanged onto the ion exchange material at the ion exchange sites. Regenerant ions, produced at the semiconductor junctions then exchange with the undesirable ions attached to the ion exchange material, and the undesirable ions migrate through the bed toward the respective anode or cathode and out of the aqueous solution. The pH of the aqueous solution can be adjusted by passing the solution through either a modified cation resin bed or through a modified anion resin bed to lower or increase the pH, respectively.
