A　Zr-based　stable　metal-organic　frameworks　DUT-67　(Zr)　was　successfully　synthesized　as　an　adsorbent　to　remove　trace　mercury　and　methylmercury　ions　in　aqueous　solution.　The　removal　efficiency　of　90%　and　55%　of　Hg2+　and　CH3Hg+　was　respectively　achieved　at　pH　6　and　55　degrees　C.　The　S　in　thiophene　has　a　relatively　weak　adsorption　capacity　for　mercury　and　there　could　be　the　slight　n-complexation　between　thiophere　ring　of　DUT-67　(Zr)　and　Hg2+　besides　physical　absorption,　while　there　only　was　physical　adsorption　between　DUT-67　(Zr)　and　CH3Hg+.　The　developed　methods　were　applied　to　remove　trace　Hg2+　and　CH3Hg+　in　the　real　water　samples,　and　the　removal　efficiency　was　from　69%　to　90%　and　from　30%　to　77%　respectively;　when　the　concentrations　of　Hg2+　was　lower　than　20　mu　g　L-1　in　the　samples,　the　remaining　mercury　concentration　was　lower　than　1　mu　g　L-1,　which　can　meet　the　standard　of　the　World　Health　Organization.
