Methods of Investigating for Iron Sulfide
Review of Literature
There has been the prevalence of several investigation methods in terms of investigating
for Iron sulfide. In different research studies it have been revealed that the application of certain
investigative processes may lead to appropriate conclusions about the research findings related to
the efficacy, usability, and nature of Iron sulfide. Certain test methods have been applied in the
past to prove the aforesaid aspects, and it has been observed that there are multiple such methods
that can eventually appease the objectives of the research studies that are related to Iron sulfide.
Considering the significant role of Iron sulfide in ushering some specific technological
changes in different spheres, it has become necessary to find out more about the use and
potential of the polymorphous substance. Bai, Zheng, Chen, and Zhao
1
emphasizing the
importance of Iron sulfides have stated that the polymorphous substances now play a key role in
spheres like geology, marine systems, material science, and in some specific life sciences, and
they have also indicated that, ―The crystal structures and phase transitions of iron-sulfur
compounds are complex and elusive.‖ It is in terms of learning more about the nature,
importance, and significance of Iron sulfide that a good number of researchers, in the past, have
applied the electrochemistry experimental method. The electrochemistry experimental method
has been proved to be a reliable one in the sphere of investigation of Iron sulfide. In the
experimental study, ―Electrochemical Investigation of the Commercial Iron Sulfide Stick –
Interaction with Complexing Ligands,‖ Renuka and Ruben
2
have applied the electrochemistry
experimental method in order to investigate iron sulfide for all those properties which are
interfacial in aqueous media that contain different ionic/complexing agents. Renuka and Ruben

2
have ca
ied on with the experiment in order to determine the potentiometric response of the
commercial iron sulfide stick in various aqueous media that are supplemented by cyclic
voltammetry and UV-visible spectroscopy along with IR spectroscopy. The researchers have
found that there is quite a significance of employing commercial iron sulfide stick in the
concerned experimental process primarily because; iron sulfide is quite stable under ordinary
conditions and by the dint of its conductivity it can be employed thoroughly as electrode.

In yet
another research study, ―The Electrochemcial Properties of Sodium/Iron Sulfide Battery using
Iron Sulfide Powder Coated with Nickel,‖ applying the electrochemistry experimental method,
Kim et al.
5
have investigated the potential of iron sulfide in the context of acting like source of
energy. In the concerned study the researchers did find that, iron sulfide coated with nickel can
e a good cost-effective option in terms of battery production. Low cost and high energy density
attery can be produced by the use of iron sulfide coated with nickel.
6
The researchers
concluded, conducting the electrochemistry experimental method that, ―The Na/FeS cell showed
a high initial discharge capacity of 525 mAh/g-FeS in the cu
ent density of 0.1C-rate.‖
7
Quite
interestingly, applying the method of Raman Spectroscopy in order to determine the reactive
nature of iron sulfide as a secondary object, in the research study, ―Raman Spectroscopy of
Mackinawite FeS in Anodic Iron Sulfide Co
osion Products,‖ Genchev and E
e
8
have found
that, ―When exposed to oxygen-containing atmosphere, the initial mackinawite FeS co
osion
product transformed under laser i
adiation to hematite, Fe2O3.‖ The researchers have suggested
that, as a characteristic nature, iron sulfur sublattice has the potential to
ing about changes in
itself with the changes that significantly take place in aged mackinawite.
9
Such conclusion is yet
another pointer to yet another characteristic of the substance under research and investigation
consideration.

Moreover, in order to examine and investigate the nature of iron sulfide, in the research
study, ―Raman Investigation of Iron Sulfides under Various Environmental Conditions,‖
applying the Raman Spectroscopic experimental method, Weber et al.
10
did find out that, iron
sulfides ―exhibit a clear trend to react with O or OH of the ambient air by building new minerals
like e.g. magnetite or hematite.‖ The researchers concluded that, ―Laser-induced heating serves
apparently as an accelerator of these chemical reactions. With measurements in vacuum it is
possible to suppress this reaction.‖
11
Weber et al.
13
, pointing towards the nature of iron sulfide
through experimenting with the method of Raman Spectroscopy, did suggest that, iron sulfide, in
various environments, react differently, and the substance has well known phases on planetary
surfaces and in meteorites.
14
Moreover, Weber et al.
15
did also suggest that, ―Iron sulfides are
difficult to study while they occur in a large range of possible oxidation states and are difficult to
investigate with Raman due to a possible laser-induced alteration and fluroscence.‖ Furthermore,
applying the SEM examination method, in the research study, ―Investigation of iron sulfide
impact crater residues: A combined analysis by scanning and transmission electron microscope,‖
Wozniakiewicz et al.
