Abstract

This study aimed to investigate the simultaneous removal of methylparaben (MePB) and propylparaben (PrPB) from effluents (each one at 16 mg/L) using a nonionic micellar system containing Triton X-114. Response surface methodology (RSM) has been carried out. Extraction results using nonionic surfactant two-phase system were considered as a function of surfactant concentration and temperature variation. Four responses were investigated: MePB and PrPB extraction yield (E), solute (Xs,w) and surfactant (Xsf,w) concentrations in the aqueous phase and the volume fraction of micellar phase (ϕC) at equilibrium. Very high extraction efficiencies (99 % for PrPB and 84 % for MePB) were achieved at optimal conditions. Thereby, the amounts of PrPB and MePB were reduced 80 and 5 times, respectively. The extraction improvement using sodium sulfate was also shown. Finally, the solute stripping from micellar phase by pH change was proved.

Kurzfassung

Ziel dieser Untersuchung war, Methylparaben (MePB) und Propylparaben (PrPB) aus Abwässern (jeweils mit 16 mg/l) unter Verwendung eines nichtionischen Mizellensystems (Triton X-114) simultan zu entfernen. Die Response-Surface-Methode (RSM) wurde durchgeführt. Die Extraktionsergebnisse unter Verwendung eines nichtionischen Tensid-Zweiphasensystems wurden als Funktion der Tensidkonzentration und der Temperaturänderung betrachtet. Es wurden vier Antworten untersucht: MePB- und PrPB-Extraktionsausbeute (E), Konzentrationen von gelöstem Stoff (Xs,w) und Tensid (Xsf,w) in der wässrigen Phase und der Volumenanteil der mizellaren Phase (ϕC) im Gleichgewicht. Unter optimalen Bedingungen wurde eine sehr hohe Extraktionswirkung (99 % für PrPB und 84 % für MePB) erreicht. Dadurch wurden die Mengen an PrPB und MePB um das 80- bzw. 5-fache reduziert. Die Extraktionsverbesserung unter Verwendung von Natriumsulfat wurde ebenfalls gezeigt. Schließlich wurde das Ablösen der gelösten Substanz aus der mizellaren Phase durch pH-Wert-Änderung nachgewiesen.
