Kinetics and mechanism of adsorption of triton x‐100 on a reservoir sand

Abstract

Adsorption of Triton X‐100 on a reservoir sand (characterised by chemical analysis and i.r. spectra to be silica) has been studied under field conditions. The adsorption behaviour is best characterised by Freundlich and Temkin adsorption models. The kinetics of adsorption is found to be very much dependent on temperature and the rate of adsorption shows an anti‐Arrhenius temperature dependence. The adsorption is proposed to proceed through Si—CH3 bond formation. Addition of common inorganic salts is found to cause maxima and minima in the adsorption isotherm and to change the shape of the isotherm.
