Abstract

Mercury pollution poses a severe threat to human health. To remove Hg<sup>2+</sup> from contaminated water, we synthesized Hg<sup>2+</sup>-trapping beads that include oligo-thymidine functionalities that can form thymine–Hg(II)–thymine base pairs on the solid support. The beads can selectively trap Hg<sup>2+</sup> even in the presence of other metal cations. More interestingly, Hg<sup>2+</sup>-trapping efficiency was higher in the presence of the co-existing cations. Thus, the developed Hg<sup>2+</sup>-trapping beads can capture Hg<sup>2+</sup> without affecting the mineral balance of water so much. The Hg<sup>2+</sup>-trapping beads presented here show promise for removing Hg<sup>2+</sup> from environmental water.
