硫

In this paper,a series of parameters as aperture、surface-area ratio to particle mass、hole-volume of pyrite (FeS2) particle,and the release characteristic of sulfur before reaction and under different temperature of drop-tube furnace were measured using ASAP2000 instrument from Micromeritics Co. USA with isothermal-absorption method. The configuration of FeS2 and its reaction products were summarized from the experiments.

The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.
