The 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 .....
