In this study, we determined nanoparticles effect on mass transfer of CH4 gas in water. We measured mass transfer every 20 seconds with Gas Chromatography and compared in 3 conditions which include nothing, SiO2@CoFe2O4 particles and SiO2@CoFe2O4 particles modified by methyl on the surface in water. The result shows nanoparticles enhanced mass transfer and solubility of gas in water. Surface modified by methyl SiO2@CoFe2O4 nanoparticle which has both of hydro phobic property and hydrophilic property on the surface made the highest effect in mass transfer and solubility of gas.
