The resulting solution was copolymerized with a sodium alginate–30% glycerol polymer matrix to produce bio-composite nanoadsorbents. Synthesis was confirmed via PSA, ZP, AFM, XRD, VSM, TGA/DTA, BET, and elasticity testing. Removal efficiency for phosphates and nitrates (initial concentration 25 mg/L) was assessed over 60 minutes.</span></span></span></span></span></span></span><br>
