Easy removing of phenol from wastewater using vegetable oil-based organic solvent in emulsion liquid membrane process

“…Also, microscope Olympus CX31 RTSF was used to analyze W/O droplet size. The general equations of phenol removal, membrane swelling and final product enrichment are as stated in Equation (1), (2) and (3) respectively:…”

“…It will cause severe effects on human being [1]. According to Mohammadi et al [2], the concentration of phenols present in the wastewater from the industries is 6-500 mg/L for refineries, 28-3900 mg/L for coal processing and 2.8-1220 mg/L for petrochemical plants. Pharmaceuticals, plastics, wood products, paints, pulp and paper industries contain 0.1-1600 mg/L phenols.…”

“…The traditional technologies include steam distillation, liquid-liquid extraction (LLE), adsorption, chemical oxidation and biodegradation, while advanced technologies include photo oxidation processes and membrane separation technologies [2]. A comparison had been made among the membrane A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT separation technologies, ultrafiltration, supported liquid membrane (SLM) and emulsion liquid membrane (ELM) which are categorized in Table 1.Among them, the ELM shows very promising in removal of phenol.…”

Assessment of the adsorption capacity of phenol on magnetic activated carbon

“…They currently make up a large part of petrochemical materials such as polycarbonates, additives, lubricants, pesticides, explosives, detergents, and antioxidants; they are also present in natural products, for example, in lignin, and can be obtained by hydrolysis. 1,2 Phenols are classified as priority organic pollutants by US Environmental Protection Agency (EPA) and the National Pollutant Release Inventory (NPRI) of Canada, because they present negative impacts to humans, animals, and aquatic life due to their high toxicity and corrosivity even at low concentrations. These pollutants are easily absorbed by the skin and can cause severe damage to human health such as irritations, burns, and cardiovascular problems.…”

PHENOL removal in refinery wastewater using mixed oxides prepared by green synthesis

“…Phenolic compounds have generally been found to be one of the most dangerous organic pollutants in wastewater from the refinery. A very low amount of phenolic compounds in water still makes it extremely toxic for human consumption (Mohamadi et al, 2015). In natural waters, the presence of phenol allows the formation of other toxic compounds through oxidation processes.…”
