  • Characterization of the coupled plasma filtration–adsorption resin cartridge Adsorptive Capacity for cytokines and inflammatory mediators: adsorption profiles from septic patient plasma and in vitro endotoxin-stimulated whole blood
    Critical Care, 2007
    Co-Authors: Sergio Livigni, D Silengo, Mariella Maio, V Perlo, Marco Pozzato, Paola Selvaggi, Luisa Sereni, Mary Lou Wratten
    Abstract:

    Coupled plasma filtration–adsorption (CPFA) is an extracorporeal therapy that uses plasma filtration associated with an adsorbent cartridge and hemofiltration in postdilution to remove cytokines and inflammatory mediators associated with septic shock and severe sepsis. We evaluated the Adsorptive Capacity of the resin cartridge to remove various inflammatory mediators and cytokines in vitro and ex vivo.

  • TiO2/TaS2 with superior charge separation and Adsorptive Capacity to the photodegradation of gaseous acetaldehyde
    Chemical Engineering Journal, 2020
    Co-Authors: Zeng Qinglong, Xiao Wang, Xiaofeng Xie, Yan Wang, Shuncheng Lee, Jing Sun
    Abstract:

    Abstract Differing from the photocatalysis of liquid contaminant, the capture of gaseous molecule is an essential factor on the photocatalytic activity because of the fast and random motion of gaseous molecule. TaS2 is a two-dimensional material with good conductivity and large specific area, which are beneficial to the adsorption of gaseous pollutant and the separation of photo-induced e−-h+ pairs. Here, P25/TaS2 (P25: commercial TiO2) was synthesized for the first time to explore the effect of the addition of TaS2 on the photocatalytic degradation of gaseous acetaldehyde. It turned out that the existence of TaS2 provided two merits: on the one side, the Adsorptive Capacity of P25/TaS2 for gaseous acetaldehyde boosted greatly with the highest Adsorptive amount of 234.4 mL, which was three times of that of P25 (76.4 mL); on the other side, the separation efficiency of e−-h+ pairs of P25/TaS2 also increased extremely with the highest photo-current response of 15.5 μA/cm2, which was almost four times of that of P25 (4.2 μA/cm2). These two merits made P25/TaS2 have superior photocatalytic activity for the degradation of gaseous acetaldehyde with the highest removal ratio of 98%, which was twice of that of P25 (48%). The cyclic experiments verified that P25/TaS2 could keep excellent cycling stability after 6 cycles usage. In addition, proved by electron spinspin resonance (ESR) analyses and radicals quenching tests, superoxide radical was the decisive active species for the degradation of gaseous acetaldehyde compared with hydroxyl radical. Briefly, this work not only created the pioneer of the application of TaS2 in the photocatalytic field but also verified TaS2 an efficient co-catalyst in gaseous photocatalysis.

  • Determination of the Adsorptive Capacity and adsorption isotherm of vapor-phase mercury chloride on powdered activated carbon using thermogravimetric analysis
    Journal of The Air & Waste Management Association, 2006
    Co-Authors: Chung-shin Yuan, Wei-ching Chen, Chung-hsuang Hung
    Abstract:

    Abstract This study investigated the use of thermogravimetric analysis (TGA) to determine the Adsorptive Capacity and adsorption isotherm of vapor-phase mercury chlochloride on powdered actiactivated carbon (PAC). The technique is commonly applied to remove mercury-containing air pollutants from gas streams emitted from municipal solid waste incinerators. An alternative form of powdered actiactivated carbon derived from a pyrolyzed tire char was prepared for use herein. The Capacity of waste tire-derived PAC to adsorb vapor-phase HgCl2 was successfully measured using a self-designed TGA adsorption system. Experimental results showed that the maximum Adsorptive capacities of HgCl2 were 1.75, 0.688, and 0.230 mg of HgCl2 per gram of powdered actiactivated carbon derived from carbon black at 30, 70, and 150 °C for 500 µg/m3 of HgCl2, respectively. Four adsorption isotherms obtained using the Langmuir, Freundlich, Redlich-Peterson, and Brunauer–Emmett–Teller (BET) models were used to simulate the adsorption of HgCl2. The com…

  • The Adsorptive Capacity of vapor-phase mercury chloride onto powdered activated carbon derived from waste tires.
    Journal of the Air & Waste Management Association (1995), 2006
    Co-Authors: Hsun-yu Lin, Chung-shin Yuan, Chung-hsuang Hung
    Abstract:

    Abstract Injection of powdered actiactivated carbon (PAC) upstream of particulate removal devices (such as electrostatic precipitator and baghouses) has been used effectively to remove hazardous air pollutants, particularly mercury-containing pollutants, emitted from combustors and incinerators. Compared with commercial PACs (CPACs), an alternative PAC derived from waste tires (WPAC) was prepared for this study. The equilibrium Adsorptive Capacity of mercury chlochloride (HgCl2) vapor onto the WPAC was further evaluated with a self-designed bench-scale adsorption column system. The adsorption temperatures investigated in the adsorption column were controlled at 25 and 150 °C. The superficial velocity and residence time of the flow were 0.01 m/sec and 4 sec, respectively. The adsorption column tests were run under nitrogen gas flow. Experimental results showed that WPAC with higher Brunauer–Emmett–Teller (BET) surface area could adsorb more HgCl2 at room temperature. The equilibrium Adsorptive Capacity of HgCl2 fo…

Four adsorption isotherms obtained using the Langmuir, Freundlich, Redlich-Peterson, and Brunauer-Emmett-Teller (BET) models were used to simulate the adsorption of HgCl2. The comparison of experimental data associated with the four adsorption isotherms indicated that BET fit the experimental results better than did the other isotherms at 30 degrees C, whereas the Freundlich isotherm fit the experimental results better at 70 and 150 degrees C. Furthermore, the calculations of the parameters associated with Langmuir and Freundlich isotherms revealed that the adsorption of HgCl2 by PAC-derived carbon black favored adsorption at various HgCl2, concentrations and temperatures.
