Abstract
An ion exchange method for the determination of lead in urine is described which involves 1) the automatic feeding of urine into an ion exchange column; 2) the concentration of lead from urine by a suitable resin; 3) the elution of lead from the resin by an acid, and 4) the subsequent determination of lead by an acceptable method. The results obtained by this method from the urines of lead-exposed persons compare favorably with results obtained by other methods. Recovery in lead-spiked urine is 90 to 100%.
