An ion-imprinted polymer for the selective extraction of mercury(II) ions in aqueous media

Abstract

2 April 2012258 of NIP, hence the expected absence of the characteristic peak in its spectrum. 111%) determined by XRF in the final washing of the IIP, suggested that Hg 2+ ions were thoroughly washed out. 158% (see Table 1). This was noted to be very high for a polymer which was thoroughly washed, and for a material to be used in trace analysis. A logical explanation to these discrepancies is that some of the mercury may have gotten bound to the structure of the polymer during synthesis, to the extent that it could not be removed by the methods that were used for washing in this study.
