“…It was shown that it is possible to modify the properties of activated carbon by SiC coating without significantly altering the adsorption capacity [28]. Furthermore, the high temperatures resistance in an oxygen atmosphere is increased when compared to uncoated activated carbon [29]. The present work presents the characterization of such coated activated carbons helping to judge possible improvements for technical applications.…”

Abstract:In this article, for the first time the chemical and mechanical properties of novel adsorbents based on the coating of activated carbons with silicon carbide are reported. The adsorbents are prepared by chemical vapor infiltration (CVI) of activated carbons with tetramethylsilane (TMS) as a precursor. A comparison of two different modified types of activated carbon, C40/4 Extra and A35/4 Extra, each infiltrated with 25%-mass at infiltration temperatures of 973.15 and 1098.15 K, respectively, is presented. Adsorption properties were characterized by measuring nitrogen isotherms and volatile organic compounds (VOC) isotherms in gas phase and excess isotherms in liquid phase. In addition, the physico-chemical properties including the bulk density, ash content, particle hardness, abrasion, conductivity, water-soluble components, and pH value were determined. Furthermore, the first experiments in a fluidized bed adsorber are presented. The results show that the adsorption properties of the modified adsorbents are mainly maintained. The particle hardness and the abrasion resistance increases with increasing infiltration temperature, which leads to an overall increasing of mechanical stability. A modification of the chemical stability as a result of the infiltration experiments is not observed.

The dyes in the effluents discharged into water bodies, aimlessly, are displeasing aesthetically and pose hazards to aquatic communities. The use of adsorption process has been adopted for effective treatment of wastewater containing dyes. The removal of Bromophenol blue (BPB), Bromocresol green (BCG), Bromocresol purple (BCP), and Bromothymol blue (BTB) dyes (a family of triarylmethane dyes) through adsorption process using several cheaply available non-conventional agricultural-waste based adsorbents was reviewed in this report. The gaps in the treatment trend further indicate the prospect of adapting various lignocellulose and other biogenic materials for the removal of Bromo-based dyes from wastewater.

“…Reference [28] found that the reverse osmosis technology in the treatment of radioactive waste liquid certain specific nuclides effect is obvious, but it is necessary to do further research on the overall purification effect of complex composition of radioactive waste water. The studies about the effect of biological technology on the treatment of radioactive waste liquid, and found that some fungi can absorb more than 99% of radioactive materials such as uranium elements [29][30].…”

Under the new situation of China's economic development, the construction of inland nuclear power is of great significance to improve the energy structure, ensure the energy supply and promote the virtuous cycle of economic development and environmental protection. This paper introduces the current situation of nuclear power development at home and abroad and the latest development trend in the field of nuclear power: International Thermonuclear Experimental Reactor (ITER) project. Analysis the structural safety, radiological impact and waste treatment three safety problems of the construction of inland nuclear power in China, and summarizes the current situation and development trend of the technology. Finally, some suggestions are put forward for the construction of future inland nuclear power plants in China.
