摘要： 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.

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.

摘要： The hybrid photocatalyst for wastewater remediation is a composite of rhodamine B and BiOBr. The rhodamine B has a concentration between about 0.1 wt % and about 1 wt % of the overall photocatalyst. The hybrid photocatalyst is made by immersing a BiOBr semiconductor in an aqueous rhodamine B solution to form the hybrid photocatalyst by sorption of the rhodamine B by the BiOBr semiconductor. In use, the hybrid photocatalyst is added to wastewater containing at least one contaminant, such as methyl orange (sodium 4-[(4-dimethylamino)phenyldiazenyl]benzenesulfonate), to form a suspension of the hybrid photocatalyst and the at least one contaminant. The suspension is then exposed to visible to light to form a slurry containing a reaction mixture in the wastewater. The slurry is then filtered to remove the reaction mixture.
