Project Inspiration
This project was inspired by the following paper:
The Sulfur Cycle
The sulfur cycle describes how sulfur is transferred through water, rocks, and living systems. This cycle heavily relies upon the different oxidation states of sulfur.
Oxidative states of sulfur:
S2-: H2S, FeS, FeS2, CuS
S0: native, or elemental, sulfur
S2+: SO
S4+: SO2, sulfite (SO32-)
S6+: SO42- (H2SO4, CaSO4), SF6
The natural passageway of sulfur to the atmosphere is through sea spray. However, the primary anthropogenic cause of sulfur in the atmosphere is the burning of fossil fuels.
Oxidation of Sulfur
Hydrothermal vents in the ocean floor emit hydrogen sulfide, which chemolithotropic bacteria use in conjunction with oxygen to create elemental sulfur or sulfate.
CO2 + 4H2S + O2 -> CH2O + 4S0 + 3H2O
CO2 + H2S + O2 + H2O -> CH2O + SO42- + 2H+
