Comparing the adsorption behaviors of Cd, Cu and Pb from water onto Fe-Mn binary oxide, MnO

Wei XU,Huachun LAN,Hongjie WANG,Hongming LIU,Jiuhui QU

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 3,   Pages 385-393 doi: 10.1007/s11783-014-0648-y

Abstract: The adsorption potential of FMBO, FeOOH, MnO for the removal of Cd , Cu and Pb in aqueous systems was investigated in this study. Comparing to FMBO and FeOOH, MnO offered a much higher removal capacity towards the three metal ions. The maximal adsorption capacity of MnO for Cd , Cu and Pb were 1.23, 2.25 and 2.60 mmol·g , respectively. And that for FMBO were 0.37, 1.13, and 1.18 mmol·g and for FeOOH were 0.11, 0.86 and 0.48 mmol·g , respectively. The adsorption behaviors of the three metal ions on the three adsorbents were all significantly affected by pH values and heavy metal removal efficiency increased with pH increased. The Langmuir and Freundlich adsorption models were used to describe the adsorption equilibrium of the three metal ions onto the three adsorbents. Results showed that the adsorption equilibrium data fitted well to Langmuir isotherm and this indicated that adsorption of metal ions occurred on the three metal oxides adsorbents limited to the formation of a monolayer. More negative charged of MnO surface than that of FMBO and FeOOH could be ascribed by lower pH of MnO than that of FMBO and FeOOH and this could contribute to more binding sites on MnO surface than that of FMBO and FeOOH. The higher metal ions uptake by MnO than FMBO and FeOOH could be well explained by the surface charge mechanism.

Frontiers in Energy 2022, Volume 16, Issue 3,   Pages 521-535 doi: 10.1007/s11708-021-0720-9

Abstract: The energy and exergy analyses of the absorption refrigeration system (ARS) using H O-[mmim][DMP] mixture were investigated for a wide range of temperature. The equilibrium Dühring ( - - ) and enthalpy ( - - ) of mixture were assessed using the excess Gibbs free non-random two liquid (NRTL) model for a temperature range of 20°C to 140°C and from 0.1 to 0.9. The performance validation of the ARS cycle showed a better coefficient of performance (COP) of 0.834 for H O-[mmim][DMP] in comparison to NH -H O, H O-LiBr, H O-[emim][DMP], and H O-[emim][BF4]. Further, ARS performances with various operating temperatures of the absorber ( ), condenser ( ), generator ( ), and evaporator ( ) were simulated and optimized for a maximum COP and exergetic COP (ECOP). The effects of from 50°C to 150°C and and from 30°C to 50°C on COP and ECOP, the , , and circulation ratio (CR) of the ARS were evaluated and optimized for from 5°C to 15°C. The optimization revealed that needed to achieve a maximum COP which was more than that for a maximum ECOP. Therefore, this investigation provides criteria to select low grade heat source temperature. Most of the series flow of the cases of cooling water from the condenser to the absorber was found to be better than the absorber to the condenser.
