A　highly　stable　graphene-like　metal-organic　framework　(BUC-17)　was　prepared　and　used　as　an　adsorbent　to　carry　out　the　adsorption　of　anionic　dyes　from　simulated　wastewater,　which　exhibited　excellent　adsorption　performance,　particularly　towards　Congo　red　(CR)　up　to　4923.7　mg　g(-1)　at　room　temperature.　It　was　used　to　fix　a　SPE　column　to　conduct　rapid　separation　of　anionic　dyes　from　an　organic　dye　matrix.　A　related　mechanism　was　also　proposed.
