Emerging pharmaceutical and organic contaminants removal using carbonaceous waste from oil refineries.

摘要: Abstract The occurrence of emerging organic contaminants (EOCs) such as chemicals in personal care products, pharmaceuticals, plasticizers, etc. surface waters is a growing global concern. discharge most EOCs not regulated, and have been shown to be toxic both human aquatic life even at low concentrations. In this work, acid-leached carbon black waste (LCBW), carbonaceous residue from petroleum refineries, was investigated potential waste-derived adsorbent for the removal EOCs. Ciprofloxacin hydrochloride, (CIPRO, antibiotic), sulfamethoxazole (SULFA, acetaminophen (ACET, pharmaceutical), bisphenol A (BPA, plasticizer) N,N-diethyl-3-methylbenzamide (DEET, insect repellent) were chosen target owing their presence relatively high concentrations well influent effluent wastewater treatment plants. LCBW, with specific area 409 m2/g, demonstrated 90–99% 10 ppm CIPRO, BPA, ACET 70–80% SULFA DEET tap water. Adsorption rapid, particularly ACET, wherein >85% adsorption occurred within 1 h contact time. To illustrate LCBW an different physical forms, ∼3 mm spherical beads encapsulated carboxymethyl cellulose matrix prepared by facile ionic gelation method performance demonstrated.
