Material and methods
2.1. Adsorbent (FeAA) and solutions preparation
A novel and low cost adsorbent, iron oxide on an activated
alumina support, was developed in the the FBR-Fenton reaction
[21]. Deionized and doubly distilled water were used throughout
this investigation. By dissolving lead nitrate in deionized water,
we obtained the lead containing stock solution (1000 mg dm−3),
which was further diluted to the required concentrations before
being used.
