In this study, a noncommercial polyetheric-structured jeffamine-based crosslinker was used by being synthesized in the synthesis of a hydrogel of a cationic-structured p[2-(acryloyloxy)ethyl] trimethylammonium chloride p(AETAC). The hydrogels containing crosslinkers with five various percentages (0.1, 0.25, 0.75, 1) were synthesized and were aimed to be used as an adsorption material. For the applications, a 1% crosslinked hydrogel (GEL 5) was utilized for the adsorption of a mono-azo chemically structured anionic characterized methyl orange (C14H14N3NaO3S) (MO) colorant. The structure of the jeffamine-based crosslinker was inspired by FT-IR, 1H-NMR, 13C-NMR, and LC-MS analysis, while the hydrogel structure characterization was elucidated by FT-IR spectroscopy. The morphological structure of the hydrogel was examined using scanning electron microscopy (SEM), SEM-EDX, and elemental mapping methods. Concurrently, the mechanical resistance of GEL 5 was tested, and its swelling behavior was examined in different media and pH values. GEL 5, considered decent adsorbent material owing to its structural qualifications, was used in the toxic MO dye adsorption process. In adsorption studies, the maximum qe value of the GEL 5 hydrogel was 547.34 ± 40.00 mg/g in 1000 mg/L MO dye solution. Furthermore, desorption studies have shown that it has reusability, which is a crucial factor in adsorbent selection.
