文摘
- •
Fluorapatite and A. niger show high ability in lead immobilization.
- •
Organic acids secreted by A. niger enhance the dissolution of fluorapatite.
- •
A. niger can survive in highly concentrated lead solution.
- •
Stable fluoropyromorphite dominates the precipitation with the reaction of dissolved fluorapatite and Pb solution.
- •
Lead oxalate can also be precipitated in the mixture of fluorapatite and A. niger.
