title: Analysis of lead and tin in strong brine and high iron systems using the microsampling technique.
abstract: The development of hydrometallurgical techniques such as the iron(III) chloride-sodium chloride system for the recovery of metals from scrap materials necessitates the analyses of these metals in a high salt medium during the recovery studies. An alternative method for the analysis of lead and tin in strong brine and high iron systems by flame atomic absorption spectrometry is a microsampling technique in combination with in situ standard addition. Relative standard deviations of 1.2% and 2.2% were obtained for the analysis of lead and tin respectively. The accuracy for the method is also satisfactory with recoveries ranging from 90% to 102%. The microsampling technique is rapid and simple, requires small volumes of sample and offers no clogging problems during the atomic absorption analyses.
