Abstract

The amphiphilic Janus-like CA-MoS2 fibrous sponges were synthesized and employed to remove oil from wastewater. The efficiency of treating 100 L of emulsion containing 10 mg/L of oil by CA-MoS2 fibrous sponge in a one pass flow through reactor was examined under different flow rate, pH and temperature conditions. The oil concentrations in the treated effluent were all below the industrial discharge requirement of 5 mg/L. The spent sponges were successfully regenerated and reused in multiple cycles. It was found that the adsorption of oil followed the Langmuir adsorption isotherm (R2 = 0.988) and pseudo-second-order kinetic (R2 = 0.995). Artificial neural networking (ANN) was developed to optimized the oil removal. The trained ANN was used to predict the oil removal of two new conditions. This study provides the basis for the development of an efficient material that can treat large volume of dilute oil containing wastewater for water reuse.
