| Abstract | ||
| Lead (Pb) pollution adversely affects the growth and welfare status of various aquatic animals. Thus, the search for treating agents having the capability to remove Pb from the polluted wastewater is worthwhile. Hence, the two-stage polyurethane foam (PU) column was applied for lead (Pb) removal from industrial wastewater. The foam was packed into a column for easier use. The effect of different factors such as the weight of foam, the contact time and the pH degree were studied. Results revealed that the lead removal percent (LRP) was the best at pH 5 and 105 minutes for 4g PU/0.01 moles lead. The highest LRP reached 88% after the first stage and 98.6% after the second stage. The foam was used for Pb removal from a real sample of industrial wastewater. 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. | ||
