Polyvinylidene Fluoride/Multiwalled Carbon Nanotubes Membrane For Methylene Blue Dye Removal Via Adsorption by Rajendren, Munesh Daniel

“…This leads to the conclusion that the adsorption process between PVDF as well as PVDF/MWCNT and the MB dye is an endothermic process. The study of the contact time between the membrane and the MB dye showed that the process begins rapidly when the concentration of the solution decreases by 5.66% in the first hour and slowly reduces in efficiency when the concentration only reduced about 2% over the next 3 hours due to the vacant adsorption sites being filled. …”

CO2 adsorption and CO2/CH4 separation using fibrous amine-containing adsorbents: isothermal, kinetic, and thermodynamic behaviours by Mohamad, Noor Ashikin, Nasef, Mohamed Mahmoud, Tuan Abdullah, Tuan Amran, Ahmad, Arshad, Ting, Teo Ming

“…H° showed positive values suggesting that the adsorption of CO2 on the present fibrous adsorbent was non-spontaneous with an increase in randomness implying that the process was endothermic. Overall, it can be suggested that PE/PP-g-PGMA/TEPA adsorbent has a strong potential for separation of CO2 from NG.…”
