| Résumé: | This method development study of tin determination in
alloys is divided into three parts, namely visible spectrophotometry,flameless atomic absorption spectrophotometry
( FAAS ) and classical methods. Visible spectrophotometry was
chosen as the main technique because atomic absorption spectrophotometry
by the flame mode ( another popular method for tin )
was known to give a lot of problems . However, FAAS using
graphite furnace was also studied in this project since this
appraoch was claimed to give better sensitivity.
The spectrophotometric method of determining tin in alloys
using catechol violet and cetylpyridinium bromide is discussed
in detail. |
