Iron dissolution kinetics of mineral dust at low pH during simulated atmospheric processing
mineral dust low pH simulated atmospheric processing
2011/2/25
We investigated the iron (Fe) dissolution kinetics of African (Tibesti) and Asian (Beijing) dust samples at acidic pH with the aim of reproducing the low pH conditions in atmospheric aerosols. The Bei...
Evaluation of simulated photochemical partitioning of oxidized nitrogen in the upper troposphere
