Removal of PB (II) Ions from Aqueous Solutions Using DSS Surfactant Via Cloud Point Extraction
One of the most important ways to extract and remove contaminants is to use surfactants. Due to the great convenience and diversity of surfactants, the method of cloud point extraction (CPE) has been considered by researchers. In this research, the cloud point extraction was accomplished for the extraction of Pb (II) ions from aqueous solutions using dioctyl sulfososuccinate (DSS) as a gemini anionic surfactant. The effective parameters such as optimum pH, cation concentration, surfactant concentration were investigated. The best condition of extraction with maximum efficiency (94.0%) was determined at pH=7.5-10, cation concentration (50 mg/L), surfactant concentration (5.0%wt).
