Oil Concentration

It is well-known that TiO2is an environmental benign photocatalyst which can be used to decompose harmful organic compounds. Recently, many studies are concentrated on the purification of industrial wastewater due to the requirement of environmental protection. In present study, TiO2nanomaterials supported by fine zeolite particles have been used as the photocatalyst to purify the oily wastewater. It has been found that the oil concentration in the modulated water can be reduced significantly and rapidly under the action of photocatalytic degradation and the ultraviolet light radiation. After 80 minutes, oil concentration in the modulated water can be reduced by more than 80%. The results suggest that TiO2nanomaterials supported by fine zeolite particles are effective material for purification of oily wastewater. In addition, the present results show that the efficiency of water purification can be significantly increased by use of mechanical stirring during the photocatalytic degradation process.

Effective removal of the organic pollutants from aqueous solution is significative and challenging for environmental sustainability. The high-performance adsorbent materials need to be developed. In this study, oxygen-rich fish-scale-like porous boron nitride (O-PBN) was facilely synthesized only at 900[Formula: see text]C (about 400[Formula: see text]C lower than that of the conventional process) through the molten salt method. The adsorption capacity of the as-prepared O-PBN for Methylene Blue (MB) from water was 422.6 mg/g, resulting from oxidizing groups and B–O bonds induced by oxygen doping as well as fish-scale-like structure composed of the BN nanoflakes. Moreover, the initial removal capacity of O-PBN only lost 7.6% even after 10 adsorption–regeneration cycles due to their strong resistance to oxidation. The unique B–O polar covalent bond, fish-scale-like two-dimensional nanostructure exposing the active adsorption sites to the surface ((002) crystal plane) and high specific surface area of O-PBN are confirmed to be the key factors in significantly enhancing water purification and regeneration performance. Overall, the synthetic method should help to a low-temperature and facile fabrication of O-PBN for effective water cleaning.
