Potentiometric determination of salicylate by using zinc aluminium 4(2,4dichlorophenoxy) butyrate nanocomposite as ion selective electrode (IR)

This study describes the construction and characterisation of zinc aluminium layered double hydroxides-4(2,4-dichlorophenoxy)butyrate (Zn/Al-DPBA) nanocomposite membrane electrode for determination of salicylate. The best performance of the membrane electrode was shown by having compositions Zn/Al-D...
