SEQUENTIAL ANALYSIS OF BLACKSHALES AND ITS APPLICATION TO BIOMINERALIZATION RESEARCH

After leaching blackshales with CHCL₃,HaAc-NaAc buffer,HCl-H₃PO₄ mixture,HCl-HP mix-ture and heavy liquid sequentially,chloroform extracted bitumen-A,carbonate,ferromanganese oxide,silicate components and kerogen are obtained respectively-The recovery of standard addition for different components ranges 86%-104.3%.The sequential analysis is applicable to,besides the study of main components in oil shales,biomineralization research.
