Electrochemical Studies of Nanoflakes like ZnMnO3 Perovskites for the Determination of Priority Organic Pollutant N-hydroxysuccinimide

Abstract

Surfactant assisted co-precipitation method active for preparing ZnMnO3 perovskites. The as- synthesized nanoflakes are well characterized by using numerous microscopic and spectroscopic methods which confirmed that ZnMnO3 has high crystalline nature, desired functional groups with nanoflakes like morphology. The synthesized ZnMnO3 were fabricated as the electrode material to determine biologically important as well as priority organic pollutant N- hydroxysuccinimide (NHS). The improved sensing performance of ZnMnO3 towards NHS with outstanding sensitivity, and selectivity in the presence of a 50-fold excess concentration of metal ions and amino acids. The NHS sensor at ZnMnO3/GCE exhibits wide dynamics ranging from 0.01 μM to 530.6 μM with a superior detection limit of 0.04 μM. Furthermore, the proposed sensor has utilized by practical applicability of NHS detection in the spiked urine samples that achieved better recoveries.
