Abstract:
A potentiometric sensor for lead(II) ions based on the use of 1,4,8,11-tetrathiacyclotetradecane (TTCTD) as a neutralionophore and potassium tetrakis-(p-chlorophenyl)borate as a lipophilic additive in plasticized PVC membranes isdeveloped .The sensor exhibits linear potentiometric response towards lead(II) ions over the concentration range of1.0105–1.0102mol L1with a Nernstian slope of 29.9 mV decade1and a lower limit of detection of 2.2106mol L1Pb(II) ions over the pH range of 3 – 6.5. Sensor membrane without a lipophilic additive displays poorresponse .The sensor shows high selectivity for Pb(II) over a wide variety of alkali, alkaline earth and transition metalions .The sensor shows long life span, high reproducibility, fast response and long term stability .Validation of themethod by measuring the lower limit of detection, lower limit of linear range, accuracy, precision and sensitivityreveals good performance characteristics of the proposed sensor .The developed sensor is successfully applied todirect determination of lead(II) in real samples .The sensor is also used as an indicator electrode for thepotentiometric titration of Pb(II) with EDTA and potassium chromate .The results obtained agree fairly well withdata obtained by AAS.
