-Transformation/dissolution, pH6 (pH that maximises dissolution)
The dissolved concentrations of aluminium and manganese at a 100 mg/l loading after 7 days were below LOD (< 0.01µg/L) for aluminium and 1.48 µg/L for manganese.
The dissolved concentrations of aluminium at a 1 mg/l loading after 7 and 28 days were 0.29 µg/L and 0.42 µg/L, respectively.
The dissolved concentrations of manganese at a 1 mg/l loading after 7 and 28 days were 10.66 µg/L and 8.91 µg/L, respectively.
