Acid, Base Accounting. ,Acid, Base Accounting procedures are used as a screening process to categorise materials into potentially ,acid, generating and potentially non-,acid, generating. For material where the potential for ,acid, generation is uncertain, humidity cell testing is performed to attempt to define ,acid, generation characteristics.

Nanoscale zerovalent iron (nZVI) has been investigated for the selective formation of Cu nanoparticles from ,acid mine, drainage (AMD) taken from a legacy ,mine, site in the UK. Batch experiments were conducted containing unbuffered (pH 2.67 at t = 0) and pH buffered (pH 99.9% removal of all metals within 1 h when nZVI ≥ 1.0 g/L) from unbuffered AMD despite the coexistent of

Acid,-,mine, drainage (AMD) is difficult and costly to treat. We investigated a new approach to AMD treatment using fuel cell technologies to generate electricity while removing iron from the water. Utilizing a recently developed microbial fuel cell architecture, we developed an ,acid,-,mine, drainage fuel cell (AMD-FC) capable of abiotic electricity generation.
