Mercury | * | 0.5 | ≈ 50# |
Nickle | 45 | 3 | > 90 |
Silver | * | 0.5 | ≈ 50# |
Zinc | 37 | 3 | > 90 |
* Undetermined capacity due to the nature of adsorption, does convert to pure metal from which recovery may be possible.# Highly dependent on other species in the stream. All figures are subject to ongoing research and updating.* Figures courtesy of Glasgow University, UK. SEE ALSO Bone Char Adsorption of Metals and Non-Metals
