摘要: Abstract A new poly(vinyl chloride) membrane sensor for Pb(II) ions based on N , ′-dibenzyl-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane ( I ) as an ionophore was prepared. The exhibits a Nernstian response lead over wide concentration range of 8.2 × 10 −6 to 1.0 × 10 −1 M with slope 30.0 ± 0.1 mV/decade activity. It has fast time about 10 s and can be used at least 3 months without any divergence in potential. electrode the pH 2.0–6.8. proposed shows fairly good discriminating ability towards comparison some alkali, alkaline earth, transition heavy metal ions. successfully applied direct determination solution indicator potentiometric titration EDTA.
