摘要

Adsorption of non-ionic surfactant (ethoxylated nonylphenol; ENP) from aqueous solution is studied at 30 ℃ using butyl rubber (II R) mixed with two types of carbon black: high abrasion furnace (HAF) and general purpose furnace (GPF) as fillers with different concentrations. The results indicate that butyl loaded with HAF is more efficient as adsorbent surface than that loaded with GPF irrespective of the carbon black concentration and the adsorption increases as the immersion time increases. The experimental data of adsorption isotherms could be fitted to the Langmuir equation below the critical micelle concentration (CMC) of ENP.
