Abstract
The tremendous popularity of porous organic polymers in all fields of Science is irrefutable these days. The current study investigates the application of an accessible covalent triazine-based polymer (CTP) synthesized from 2,4,6-tris(hydrazino)-1,3,5-triazine (THT) and terephthaldehyde (TA) in a Pyrex sealed tube. The prepared CTP can efficiently remove the Cu(II) ions from aqueous solutions. After the successful CTP synthesis, it was characterized using different methods, including FE-SEM, XRD, CO2 adsorption isotherm, and TGA. A wide range of pH with different adsorbate concentrations and times were investigated to study the batch adsorption experiment. The excellent adsorption of Cu(II) ions at the optimal pH of 7 with a maximum capacity of 86.95 mg. g− 1 and excellent thermal stability makes it the right industrial investigation choice. Moreover, the obtained data reveal that the adsorption isotherm obeys the Langmuir model, and the adsorption kinetics obeys the pseudo-second-order model.
