Waste Adsorbent Valorization of Biopolymer‐Modified Zn–Fe Layered Double Hydroxides for Crystal Violet Removal and Enhanced Nonenzymatic Urea Detection
Finding suitable and inexpensive bifunctional materials that can act as adsorbents for crystal violet (CV) removal and as electrocatalysts for the electrochemical detection of urea remains one of the contemporary challenges. Waste valorization of spent wastewater nanoadsorbents is a promising route toward achieving c...
