Arsenic speciation in sulfidic waters; some current problems.
Presenting person: Prof. Dr. George Helz, University of Maryland (Homepage)Fr. 2014-10-17 (08:15-09:45), S 137 (NW III)
Employing a thermodynamic perspective, the speaker will review current limits to our understanding of the chemical behavior of arsenic in sulfidic natural waters. Some questions discussed will be,
- Why do thioarsenates occur in sulfidic waters?
- Why are sulfosalt minerals common in ore deposits?
- What is the role of zerovalent sulfur and polysulfides in arsenic speciation?
