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.

Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
