Synthesis of Chitosan Protected Nickel Hexacyanoferrate Modified Titanium Oxide Nanotube and Study its Application on Simultaneous Electrochemical Detection of Paracetamol and Caffeine
The nickel hexacyanoferrate decorated titanium oxide nanotube (NiHCF@TNT) was prepared by ion exchange method by mixing of nickel ion modified titanium oxide nanotube with a known amount of potassium ferricyanide under stirring over a period of 5 h. The resulting product was isolated and then characterized with XRD, FT-IR and SEM. The electrochemical behaviour of NiHCF@TNT was investigated by cyclic voltammetry using chitosan as stabilizing agent. The electrocatalytic property of chitosan protected NiHCF@TNT was carried out on electrochemical oxidation of paracetamol and caffeine simultaneously. The proposed method may be applied for the electrochemical detection of paracetamol in drug samples. _______________________________________________________________________________
