Research suggests that wastewater is highly polluted by Hg2+, threatening the sustainability of our environment and health conditions human beings. However, most existing adsorbents have a poor adsorption performance require expensive raw materials. A low-cost adsorbent material with very high therefore an urgent need. In this work, we successfully prepared thiophene-based porous triazine polyamide (Tb-PTPa) for first time, using two inexpensive materials simple amidation reaction. Tb-PTPa was then used efficient Hg2+ in aqueous media. The capacity up to 2562 mg g-1 rate 12.9 min-1. addition, shows good selectivity Hg2+. removal still higher than 91% after five cycles. interfering substances present water only slightly affect capture Tb-PTPa. combination experimental results density functional theory calculations clearly introduction amide bonds can greatly enhance chelating ability N atoms S thiophene Based on extensive investigation, demonstrated excellent properties. Therefore, expected be new treatment wastewater.
