20150174567 | HYBRID PHOTOCATALYST FOR WASTEWATER REMEDIATION - 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. | 06-25-2015 |
20150175444 | WASTEWATER FILTRATION SYSTEM AND METHOD - 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. | 06-25-2015 |

20150196788 | 450 NM VISIBLE LIGHT-INDUCED PHOTOSENSITIZED DEGRADATION OF RHODAMINE B MOLECULES OVER BIOBR IN AQUEOUS SOLUTION - A method for degrading Rhodamine B including: mixing BiOBr and Rhodamine B; and irradiating the mixture with a radiation having a wavelength of from 440 nm to 554 nm. The Rhodamine B may be in an aqueous solution. The BiOBr may be added to the aqueous solution of Rhodamine B in an amount of from 0.2 to 0.5 mg/ml. The BiOBr may have a sheet-like structure with particles having a diameter of from 3 μm to 5 μm. The BiOBr may be in a pure crystal tetragonal phase. | 07-16-2015 |
