Quantitative determination of lead in mixtures of lead(ii) halides using solid-state 207Pb NMR spectroscopy

Abstract

We demonstrate a multi-spectrum technique for facile, quantitative determination of lead in solid materials using solid-state ²⁰⁷Pb NMR that avoids the major problem of uniform excitation across a wide spectral range; the method can be employed without chemical separation or other chemical manipulations and without any prior sample preparation, resulting in a non-destructive analysis, and producing results that are in agreement with gravimetric analyses of mixed samples of the lead halides.
