Silicate-based adsorbents offer significant advantages over traditional materials, particularly due to their superior thermal and chemical stability, enhanced regenerability, the ability endure more rigorous operating conditions. In this study, an amorphous Na–Ca–magnesium silicate adsorbent (SAAM) its g-C3N4-modified counterpart (gCN-SAAM) were synthesized via alkali activation a subsequent process, respectively. The g-C3N4 modification resulted in novel hybrid with remarkable methylene blue (MB) adsorption capacity of 420 mg g–1, four times higher than unmodified sample, setting new benchmark. Solid-state 29Si (MAS CP/MAS), 1H MAS, 13C CP/MAS NMR spectroscopy used investigate complex structures these interactions MB. local structure SAAM primarily consists Q3 Si units, minor Q0 Q1 species, structural water, Mg–OH sites. Exposure MB caused upfield shift spectrum resonances high-field region, indicating interaction MAS spectra revealed between water molecules geopolymer-like framework treatment urea produce gCN-SAAM polymerization species increased relative fraction Q4 This also reduced intensity some showing g-C3N4. After on gCN-SAAM, NH2 groups disappeared, shifts C2N-NHx C3N sites indicated involvement adsorption, while remained intact. method creates sustainable, cost-effective efficient for removal from wastewater. Multinuclear provides detailed insights into adsorbent's interactions, potentially guiding design improved future adsorbents.
