Abstract

Marwa M. Qayed

The preparation of Iron (III) and Aluminum (III) adsorbents by impregnating two solvents namely, tri-octylamine (TOA) upon Polyurethane foam (PU) and charcoal (C) (charcoal) The relevant factors affecting solvents impregnation process including, solvents concentration, shaking time, volume/mass ratio, impregnation temperature and type of diluents were studied. Also, the adsorption characterization of the prepared adsorbents has studied. The optimum conditions affecting adsorption of Iron (III) and Aluminum (III) at pH of 3, temperature of 25°C for 1h and m/v ratio 10 g/L were the best conditions to remove Iron (III) and Aluminum (III). crude phosphoric acid (WPPA) used as a case study and showed a decrease in Iron and Aluminum from 8500 mg/L and 4234 mg/L to 5117 mg/L and 2012 mg/L.
