New application of magnetite nanomaterial for a cationic surfactant removal from wastewater

The paper presents the adsorption capacity of magnetite nanomaterial for a cationic surfactant removal
from wastewater. Kinetic studies were performed by adding the magnetite nanomaterial to a wastewater solution of benzethonium chloride having the concentrations of 2 mg/L and 20 mg/L. The wastewater systems were investigated at 1, 2, 4, 6, 24 and 48 h. The highest removal efficiency (86,98%) was obtained for wastewater containing 2 mg/L benzethonium chloride concentration. The results obtained for the magnetite nanomaterial demonstrates the possibility of applying this nanomaterial for the removal of benzethonium chloride cationic surfactant from wastewater.
