The external and interlamellar spaces of montmorilonite (MMT) were used as solid support for synthesis of CuO nanoparticles (NPs) at room temperature by the chemical reduction method. In this project, Copper Nitrate plus water (Cu(NO3)2. xH2O) and Sodium Hydroxide (NaOH) were used as Copper precursor and reducing agent respectively. Then, MMT/Cu2+ nanocomposites were stabilized with different r...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
