Boehmite nanopowder recovered from aluminum cans waste as a potential adsorbent for the treatment of oilfield produced water

Abstract In the present study, high surface area boehmite nanopowder was recovered from aluminum cans waste. The sodium aluminate solution first prepared by dissolving in NaOH and then, H 2 O added to precipitate boehmite. characterized means of X-ray diffraction (XRD), transmission electron microscopy (TEM) N adsorption–desorption techniques. thermal stability sample investigated using thermogravimetry (TG) differential scanning calorimetry (DSC) feasibility powder as a new low-cost adsorbent for treatment oilfield produced water investigated. For comparison, commercial activated carbon used under same conditions. efficiency both determined monitoring values number pollution indicators [i.e. turbidity, sulfides, sulfates, total organic (TOC), petroleum hydrocarbon (TPH), chemical oxygen demand (COD)] before after treatment. showed very good water, which is close that effect dose, time, pH media on adsorption examined at room temperature indicator. maximum capacity COD reduction 69.6% 83.5% 40 g/l dosage, pH7, 24-h contact time.
