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 …

The iron sulfides constitute a diverse group of solids and dissolved complexes many of
which play key roles in marine systems. The group is particularly complex in the lower …

Existing redox classifications and the calibrations of elemental proxies to modern
environmental redox scales are in need of re-evaluation. Here, we review environmental …

Pyrite framboids are densely packed, generally spherical aggregates of submicron-sized
pyrite crystals. In this study, a survey was made of framboid size distributions in recently …

The association of dissolved sulfate and hydrocarbons is thermodynamically unstable in
virtually all diagenetic environments. Hence, redox-reactions occur, whereby sulfate is …

The pyritization of reactive trace elements in different anoxic marine sediments was
investigated to determine the importance of factors such as∑ H 2 S, reactive-Fe, pyrite …

The addition of iron is a convenient way for removing phosphorus from wastewater, but this
is often considered to limit phosphorus recovery. Struvite precipitation is currently used to …

Iron-based materials used in water treatment and groundwater remediation especially
micro-and nanosized zerovalent iron (nZVI) can be more effective when modified with …

Interactions of trace metals with sulfide in anoxic environments are important in determining
their chemical form and potential toxicity to organisms. In recent years, a considerable body …

Pyrite framboid formation may be the result of four consecutive processes:(1) nucleation and
growth of initial iron monosulfide microcrystals;(2) reaction of the microcrystals to greigite …
