Description Lead (II) is the hazardous and toxic material for human being and animals since it damages the central nervous
system causing disorder of the circulatory system and brain. Hence to overcome the toxic effects of lead, rapid,
simple and effective methods to detect Pb (II) is necessary. Pb (II) ISE membrane was prepared by the use of
polyaniline-zirconium (IV) iodate composite cation-exchange material. To prepare this electrode, a solution
casting method was used, and the prepared electrode was subjected to different characterisation techniques
including SEM, XRD and FTIR. Outstanding results were obtained for properties such as porosity, thickness,
water content, electrical conductivity and swelling. The membrane was found to have a working concentration
ranging between 1×10−12 M and 1×10-1 M, and the Nernstian slope was obtained as 29.28 mV which lead to
change in ion concentration. It showed good stability and can be used for six months without any deviance. The
experimental studies showed that the response time is very fast, i.e. 10 s for lead ion concentration ranges from
1×10-8 to 1×10-1 M. It has been studied for concentration ranging at 1×10-1 M, and 1×10-3 M with a pH
ranging between 2.5 and 6.5 and it was found to operate successfully. It exhibited good reproducibility as well as
the detection limit.
