Abstract : The influence of different parameters e.g. contact time, pH, sorbent doze and competing ions that control the retention profile of mercury (II) from aqueous solution, onto some selected local soil solid sorbents collected from Saudi Arabia, as solid scavenger of heavy metals released from environment, was critically investigated. The uptake of mercury (II) species onto the employed solid sorbent was found fast and followed a first-order rate equation. The sorption data of mercury (II) onto the solid sorbents followed Freundlich type sorption isotherm. Thus, sorption mechanism involving “surface adsorption” mechanism seems a more likely retention model. The cellular structure of the PUFs sorbent offer unique advantages over conventional bulk type sorbents in rapid, versatile effective separation and/or pre-concentration of gold ions. The proposed solid sorbent could be packed in column mode for quantitative collection of trace and ultra trace mercury (II) concentration from different water including wastewater.
