A universal, scalable, solvent-free, one-step method for thermal annealing a stainless steel membrane to create a superhydrophilic surface. The superhydrophilic membrane itself, and methods for using it to separate oil and water in an oil and water mixture or for photocatalytic degradation of methylene blue and other organic contaminants.

One-step scalable fabrication of mechanically robust visible-light responsive oxide-modified metallic multifunctional membranes

An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.

Alumina/NiO/ZnO and Alumina/ZnO are synthesized via a novel modified hydrothermal method and investigated for the desulfurization activities. Sulfur compounds such as thiophene, benzothiophene (BT) and dibenzothiophene (DBT) are tested for their removal from model diesel fuel. The prepared composite materials were examined by the means of N-adsorption, X-ray diffraction and Fourier transform infrared spectroscopy.

The wastewater filtration system and method relates to systems and methods that use Ruba Al-Khali Saudi sand as the filtration media in systems for treating industrial wastewater. Ruba Al-Khali Saudi sand is effective in removing organic dyes, particularly rhodamine B, from the wastewater. The method includes bringing wastewater having an organic dye constituent into contact with the Saudi sand for a period of time sufficient to adsorb the organic dye. The system may include a batch reactor, such as a fixed bed or moving bed reactor, or a continuous flow reactor, such as a column reactor. When a batch reactor is used, the method may benefit from shaking or agitating the filtration media, particularly in the dark or under low ambient light conditions. The method may include regenerating the Saudi sand after use by heating the filtration media.

The method for detection of cyanide in water is a method for the detection of a highly toxic pollutant, cyanide, in water using ZnOnanoparticles synthesized locally by an elegant Pulsed Laser Ablation technique. ZnOnanoparticles having a median size of 4 nm are synthesized from pure zinc metal target under UV laser irradiation in a 1-10% HOenvironment in deionized water. The synthesized ZnOnanoparticles 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 ZnOnanoparticles on a metal electrode. The electrode is used for cyanide detection.
