Synthesis, Characterisation, and Performance of Polyaniline (PANI) in Metals Sorption

Abstract:

PANI was prepared in-house, characterized and utilized in the sorption of calcium, magnesium, iron, and copper in aqueous solution. The objective of this research was to evaluate adsorption of metals in mono and multi-metal in aqueous solutions onto PANI. Literature has it that, there is no record for competitive sorption of metals by PANI. The characterization of the prepared PANI confirmed with other literature that it was the Emeraldine PANI that was prepared. The results obtained after the multi metal adsorption experiment showed that PANI has a good performance in the removal of copper, iron, calcium, and magnesium, and can be credited to its' large surface area since it is a nanomaterial. Testing for the selectivity showed that the prepared nanoPANI adsorbed 95.2% of lead, 93.8% of copper and 75.8% of the iron in the single metal system.
