Summary: | Direct and indirect releases of large quantities of surfactants to the
environment may result in serious health and environmental problems.
Therefore, surfactants should be removed from water before release to the
environment or delivery for public use. In the present work, the removal of
anionic surfactants, benzene sulfonate (BS), p-toluene sulfonate (TS) and
4-octylbenzene sulfonate (OBS) from water by adsorption onto Amino modified
mesoporous carbon (AMC) were studied. The AMC surface chemistry and textural
properties was characterized by nitrogen adsorption, XRD and FT-IR analyses.
Experiments were conducted in batch mode with the variables such as amount of
contact time, solution pH, dose of adsorbent and temperature. Finally, the
adsorption isotherms of anionic surfactants on mesoporous carbon adsorbents
were in agreement with a Langmuir model. AMC has shown higher anionic
surfactants adsorption capacity than the untreated mesoporous carbon, which
can explain by strong interaction between anionic surfactant and cationic
surface of adsorbent.
