Reduction in the growth rate of a hydrate film at the interface of liquid CO2 and an aqueous solution of humic acids in comparison with that with pure water and sodium dodecyl sulfate solution

The rates of growth of a hydrate film on the contact surface of an aqueous phase and liquid carbon dioxide were studied. In 0.1% solutions of humic acids, the film growth rate was lower by a factor of approximately 4 than that in pure water and a 0.1% solution of sodium dodecyl sulfate. Possible reasons for the decrease in growth rates are briefly discussed.
