A substoichiometric radioisotope dilution study using 21OPb
Description
A radioisotope dilution procedure was developed which permits the determination of lead over a concentration range of 0.1 to 10 ppm. Samples in an ammoniacal cyanide/sulfite medium are labelled with 210Pb, followed by addition of substoichiometric amount of dithizone. The Pb(HDz)2 formed is extracted into CH2Cl2, and aliquot portions are taken for liquid scintillation counting. Count rate is plotted vs. the reciprocal of the lead concentration, yielding a straight line. An average error of +-3.5% is estimated, based on a linear least squares fit. (author)
