Acidic deposition: decline in mobilization of toxic aluminium

The mobilization of aluminium from acidic forest soils is arguably the most ecologically important consequence of acid deposition in the environment because of its adverse effects on soils, forest vegetation and surface water. Here we show that there has been a significant decline in the concentrations of aluminium species in soil solutions at mediumto

this paper, we investigate the magnetron sputtering deposition of an Allayer on Zrdoped FeOOH (ZrFeOOH) samples to fabricate a Zr/Al codoped Fe2O3 (AlZr/HT) photoanode. An Allayer is deposited onto ZrFeOOH through magnetron sputtering and the thickness of the Al deposition is regulated by differing the sputtering time. Electrochemical
