Abstract

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. D 2004 Elsevier B.V. All rights reserved.
