Sodium lauryl sulfate (SLS) is one of the main components present in detergents
and personal hygiene products, therefore, it is the most common anionic surfactant
substance in municipal wastewater, which during discharge endanger flora and
fauna of the recipient.
During the present study, adsorption of sodium lauryl sulfate (SLS) was performed
from the wastewater suspension model sample onto powdered activated carbon
(PAC). The experiment was performed at room temperature (20°C) and the pH
value range of the initial model samples from 6,40 to 7,51. The influence of
adsorbent dose (PAC), the adsorbate concentration (SLS), and adsorption time on
the removal efficiency of SLS from the model sample were monitored. The process
was additionally controlled by measuring the pH value.
The use of powdered activated carbon gives satisfactory results in the removal of
sodium lauryl sulfate from water, and the presented results of this research can
serve as a foundation for further testing and implementation of this adsorption
process for the removal of anionic surfactants from real wastewater samples.
