Highly efficient adsorption of direct Scarlet dye using guanidinium-based covalent organic polymer

Characterization of TA–TG_Cl

In the first stage, FTIR spectrum was employed to affirm the preparation of the TG_Cl compound. In this regard, As evidenced in Fig. 2, double peaks at 3319 and 3208 cm⁻¹ are assigned to…
