Retention Profile of Mercury (II) Ions from Aqueous Solution onto Some Selected Local Solid Sorbents

The influence of different parameters e.g. contact time, pH,sorbent doze and competing ions that control the retention profile ofmercury (II) from aqueous solution, onto some selected local soil solidsorbents collected from Saudi Arabia, as solid scavenger of heavymetals released from environment, was critically investigated. Theuptake of mercury (II) species onto the employed solid sorbent wasfound fast and followed a first-order rate equation. The sorption dataof mercury (II) onto the solid sorbents followed Freundlich typesorption isotherm. Thus, sorption mechanism involving “surfaceadsorption” mechanism seems a more likely retention model. Thecellular structure of the PUFs sorbent offer unique advantages overconventional bulk type sorbents in rapid, versatile effective separationand/or pre-concentration of gold ions. The proposed solid sorbentcould be packed in column mode for quantitative collection of traceand ultra trace mercury (II) concentration from different water including waste water.
