Contamination of water by Pb 2 + and the threat invasive vegetation affects quality quantity accessible to all life forms has become a primary concern South Africa world at large. This paper synthesized, characterized, evaluated resins from tannin-rich Acacia species as an environmentally benign adsorbent. The analysis pore volume surface area reveals small dimension 9 × 10−3 cc/g large (2.31–8.65 m2/g), presenting suitable physical parameters for adsorption . Langmuir model offers best...
Quantity of water is a major concern, but the quality more urgent concern due to heavy metal pollution. In this study, focus was develop adsorbents (tannin resin (TR) and iron-doped tannin (Fe-TR)) from invasive Acacia mearnsii for Pb2+ Ni2+ in solution. The developed TR Fe-TR were prepared directly by crosslinking iron-grafting; respectively with thermal stable at ≤ 350 °C. Surface functionality analysis revealed presence chelating groups ≈ 1688 3661 cm−1. crystallite sizes smaller compared...
