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.

Robust chemical modification of mesoporous silica was conducted using 3-mercaptopropyltriethoxysilane via a surface-engineered postgrafting KIT-6 with acidic propylsulfonate groups to obtain KIT-6-SO3H. A fabricated meso-KIT-6-SO3H-modified quartz crystal microbalance sensor KIT-6-SO3H layers coating on QCM electrode is utilized detect Pb2+, Cd2+, and Cs+ ions high sensing affinity. The functionalized KIT-SO3H exhibits adsorption capacities (Qe) 123.5 mg g-1, 117.5 90.6 g-1 for Cs+, respectively, as determined by UV-vis measurements. These values coincide well those obtained from the ICP-OES remarkable ability adsorb metal achieved synergistic cooperation large pore volume, surface area, abundant -SO3H within structure comprehensive study carried out investigate influence pH uptake ions. Kinetic isotherm studies demonstrate that adsorptive removal follows second-order kinetic model described Langmuir isotherm, reflecting monolayer behavior. Density functional calculations reveal these metals highly exothermic thermodynamic perspective, which aligns supports experimental findings. All were exothermically adsorbed binding energies -1.790 eV -0.181 -3.113 confirming exergonic investigated
