Banana Peel Derived Chitosan-Grafted Biocomposite for Recovery of NH₄⁺ and PO₄^3–

pH-Responsive Biocompatible Fluorescent Hydrogel for Selective Sensing and Adsorptive Recovery of Dysprosium

“…The maximum AC, i.e., q max , is found to be 42.09, 38.97, 36.53, and 34.27 mg g –1 at 298, 303, 308, and 313 K (Figure a and Table ), respectively. Again, the better fitting of kinetics data with pseudo-second-order kinetics model compared to pseudo-first-order kinetics model (Figure b) and attainment of the activation energy of 70.03 kJ mol –1 (Figure d) confirm chemisorption of Dy­(III) by AGO-EPH . , The presence of −COO – /–CONH 2 /–CONH – functionalities from EPH and −NH 2 /–NH– of AGO were involved in chemical bonding with Dy­(III), as observed earlier from material characterization data. The k 2 values are found to increase with the increase in temperature, confirming the faster adsorption at higher temperatures.…”

Ammonium release in synthetic and human urine by a urease immobilized nanoconstruct

“…The robust performance of Urease/GA/CS/MIONPs is encouraging for urine treatment under ambient conditions facilitating subsequent harvesting of the ammonia. 64 In particular, the deployment of immobilized urease coupled with adsorptive extraction of the released NH 4 + suggests is an attractive approach towards human liquid waste management and is currently being investigated in our laboratory.…”
