Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Bioleaching of metal sulfides is performed by diverse microorganisms. The dissolution of
metal sulfides occurs via two chemical pathways, either the thiosulfate or the polysulfide …

The inefficiency of nitrogen removal in pyrite autotrophic denitrification (PAD) and the low
efficiency of PO 4 3−-P removal in sulfur autotrophic denitrification (SAD) limit their potential …

In this study, denitrification was performed using pyrite as sole electron donor. The nitrate
reducing rate ranged from 0.61 to 0.95 mM/d. The production of nitrous oxide (N 2 O) was …

Pyrite autotrophic denitrification (PAD) represents an important natural attenuation process
of nitrate pollution and plays a pivotal role in linking nitrogen, sulfur, and iron cycles in a …

Simultaneous nitrate and phosphorus removal can be completed by pyrite-and influent
organics-involved mixotrophic denitrification and chemical phosphorus removal via iron …

Pyrite autotrophic denitrification (PAD) is considered a promising method for nitrate removal
from wastewater and groundwater. However, the results of PAD studies have been …

Pyrite with acid-washed surfaces is chemically inert toward aqueous U (VI) at routine
conditions. Given that there is a strong radiation field in the nuclear waste repository, the …
