Hydrazine imprinted electrochemical sensor based on cobalt-barium stannate nanoparticles incorporated-functionalized MWCNTs nanocomposite for hydrazine determination in tap water samples.

ABSTRACT: A hydrazine (HYD) detection method is presented based on molecularly imprinting polymers (MIPs) and cobalt-barium stannate nanoparticles incorporated-functionalized MWCNTs (CBSNPs/f-MWCNTs) nanocomposite. Firstly, co-precipitation and sonication techniques were applied to the preparations of CBSNPs and CBSNPs/f-MWCNTs nanocomposite, respectively. Since waste generation occurs at a minimum level in these techniques, an environmentally friendly nanocomposite was prepared. After the glassy carbon electrode modification with CBSNPs and CBSNPs/f-MWCNTs nanocomposite, HYD imprinted electrodes were fabricated using cyclic voltammetry (CV) with a dispersion containing 100.0 mM pyrrole (Py) monomer and 25.0 mM HYD molecule. The resulting electrochemical sensor demonstrated a detection span of 1.0 ×
