Role of Reactive Extraction in Removal of Phenol from Wastewater
Abstract: Phenol is one of the most common organic water pollutants as it is highly toxic even at low concentration. Also, its presence in natural water can lead to the formation of substituted compounds during disinfection and oxidation processes. Reactive extraction method is found to be a capable alternate for separation of medium (300–3000 mg/l) to high (3000–6000 mg/l) concentration of phenol. The degree of extraction depends on nature of extractant, …
