Abstract

cavity. Moreover, the sensor exhibited high interfering tolerance and was successfully applied to determining metal ions in real water matrices with satisfactory recovery rates (97.37% to 100.73%). Furthermore, this sensor was found to be effective in recovering Ag(i) from leachates of electronic waste, suggesting its broader applicability in urban mining and resource recovery. These findings suggest a promising alternative valorization strategy for rice husk biomass into high-value functional materials for advanced environmental monitoring applications.
