A highly selective and sensitive disposable carbon composite PVC-based membrane for determination of lead ion in environmental samples

A Pt wire coated with phenyl hydrazone derivative–carbon composite in a poly(vinyl chloride) membrane was used for detection of lead. The sensor had a Nernstian slope of 29.46 ± 0.41 mV/decade over a wide linear concentration range of 7.7 × 10 −7 to 1.0 × 10 −1 mol L −1 for Pb(NO 3) 2. The detection...
