Regarding the adsorption tower in the process of adsorption as a research object, based on the characteristics of gas flow and heat transfer in the process of adsorption, the mathematical model was established in the process of adsorption according to the theories of thermodynamics, fluid mechanics and heat transfer. Through numerical solution, the changes of temperature, pressure and adsorption capacity...
This paper introduces, for the first time, electrodeposited gold as a new adsorbent material for micro preconcentration applications. The thin film gold layer serves as both an adsorbent and a resistive heater thus allowing self-heating capability without the need for additional off or on-chip heaters. The self-heating adsorbent enhances the desorption efficiency, reduces power consumption, and is...
The batch and dynamic adsorption of powdered activated carbon (PAC) as an adsorbent to eliminate the PFOA from the water for reuse has been studied. The first 100 mL influent (0.5 mmol/L) was totally adsorbed (100%) and more than eighty percent adsorption of PFOA was observed in the next 101-230 mL influent. The static adsorption capacity and the breakthrough capacity were 104.6 mg/g and 95.22 mg/g...
