| Description |
This study has been undertaken to understand the precise nature of association of lead in high
sulphur Assam coal. Sequential extraction of lead with ammonium acetate, HCl and RuCl 3 solutions
havebeen carriedout. RuCl3 hasbeenusedasasuitable reagent fortheextractionoflead.Itisfound
thattreatment ofsamplewithCCl 4increasestheextractionofleadbyRuCl 3solution. Theamountof
leadinthecoalstudiedvariesbetween43.2and50.4ppm.Ithasbeenfoundthatleadispredominantly
occurring in coals in association with organic matter and needs concerted attention to understand its
bio-availability. The chemical principles involved therein are also discussed.
