AbstractThe purpose of this study was to determine simultaneously of bisphenol A and uric acid by
zinc/aluminium-layered double hydroxide 2(2,4-dichlorophenoxy)propionate paste electrode. The
morphology of the electrode materials was performed by using scanning electron microscopy
and transmission electron microscopy. The electrochemical performance of modified paste
electrode was studied by using cyclic voltammetry, square wave voltammetry, electrochemical
impedance spectroscopy and chronocoulometry. Special importance effecting sensitivity and
selectivity of the modified electrode must evaluated via optimization conditions which include
effect of modifier composition percentage (15%), types of supporting electrolyte (PBS), pH of
electrolyte (6.0) and square wave voltammetry parameters that encompassed of frequency
(180Hz), pulse size (80mV) and step increment (7mV). The square wave voltammetry .....
