Two-Stages Poly Urethane Column for the Removal of Lead from Industrial Rejection Water

Article scientifique 2023 Anglais

Résumé

Abstract Two-stages poly urethane foam (PU) was applied for removal of lead from industrial rejection water. The foam was packed into a column for easier use. The effect of different factors such as the weight of the foam, the contact time, the pH factor and the presence of other salts were studied. Results clear that the lead removal percent (LRP) was the best at pH 5, 105 minutes, for 4g PU/0.01 moles lead. The highest lead removal percentage (LRP) value reached 88% after the first stage and 98.6% after the second stage. The foam was used for Pb removal from real sample of industrial waste water. The LRP range was 62.1- 88.2% for the tested samples after the first stage and 85.6-98.6% after the second stage.
