Abstract

Cellulose derivatives are one of the carbohydrate polymers which received a great interest in the construction of nanostructured materials. Particularly, the ethyl cellulose provides an enormous support to the metal nanoparticles. To the best of our knowledge, this is the first time report for the simple and rapid synthesis of ethyl cellulose (EC) supported platinum nanoparticles (PtNPs) for the determination of non-enzymatic hydrogen peroxide (H₂O₂). The PtNPs/EC composite was confirmed by various characterizations such as fourier transform infra-red spectra, energy dispersive X-ray spectra, field emission scanning electron microscope and cyclic voltammetry. Further, the PtNPs/EC composite modified glassy carbon electrode (GCE) was successfully determined the H₂O₂ with the linear concentration range from 0.05μM to 2.22mM and the lowest detection limit of 0.01μM. Moreover, the PtNPs/EC/GCE sensor electrode manifested an acceptable sensitivity, selectivity and reproducibility. In addition, we have determined the H₂O₂ in contact lens solution and human blood serum samples.
