Activated Carbon is a water treatment adsorbent with a large adsorption capacity, its adsorption capacity will be able to greatly enhance after modified activated. Through the use of before and after the modification of mesoporous activated carbon powder to the heavy metals copper ion adsorption, the effects of different pH, adsorption temperature, balance time, the amount of activated carbon adsorption...
Through the research on the adsorption of heavy metal ions in electronic industrial wastewater and the thermodynamics by activated carbon, influences of contact time, temperature, pH value and coexistence heavy metal ions on Cu2+, Pb2+, Zn2+ and Cr6+ adsorption were investigated in terms of experiments. The results showed that the copper adsorption onto activated carbon achieved equilibrium gradually...
A new adsorbent was developed from municipal sewage sludge (SS) combined with 5-20% pyrolusite of the weight of SS carbon, and using ZnCl2 as chemical activation reagent. Characterized by N2-BET methods and SEM, the result showed that the surface area of the new adsorbent was increased to 354.198 m2/g compared with that of the unmi- xed sludge activated carbon 232.526 m2/g and total pore and micropore...
CuO-ZnO-La2O3/activated carbon (AC) adsorbent was prepared and used for efficient adsorption removal of PH3 at various temperatures in the presence of O2. The feasibility of water and thermal regeneration of a spent CuO-ZnO-La2O3/AC adsorbent was also investigated. The influences of regeneration temperature, water concentration and calcination time were done on the spent CuO-ZnO-La2O3/AC adsorbent...
Phosphine (PH3) is one of highly toxic air pollutants, commonly produced in phosphorous chemical industry. In order to utilize high concentration CO in yellow phosphorus tail gas, metals (Cu, Fe and Ce) loaded activated carbon adsorbents were prepared for the adsorption of PH3 in this study. The operating conditions, such as oxygen content, adsorption temperature and space velocity, which influenced...
