Abstract

In this paper, we report a novel electrochemical sensor for the sensitive detection of hydrochlorothiazide based on La3+/ZnO nanoflower supported on graphite screen printed Electrode. Firstly we reported the synthesis and characterization of La3+/ZnO nanoflower. The as-synthesized nanostructures. La3+/ZnO nanoflower was employed to modify the screen printed electrode and demonstrated its excellent electrocatalytic activities towards hydrochlorothiazide ( HCT). Voltammetric measurements were utilized to assess the electrochemical properties towards the hydrochlorothiazide detection. The resulting sensor exhibits excellent sensitivity. Finally, this modified electrode was effectively applied to determine hydrochlorothiazide in real samples with good recoveries.
