2-Cyanoanilinium perchlorate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
In the title compound, C(7)H(7)N(2) (+)·ClO(4) (-), the cation is almost planar (r.m.s. deviation = 0.042 Å). In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to (100) by N-H⋯O hydrogen bonds.

Transposon and Deletion Mutagenesis of Genes Involved in Perchlorate Reduction in Azospira suillum PS

mBio, 2014
Although much work on the biochemistry of the key enzymes of bacterial perchlorate reduction, chlorite dismutase, and perchlorate reductase has been published, understanding of the molecular mechanisms of this metabolism has been somewhat hampered by the

Mitigating Sulfidogenesis With Simultaneous Perchlorate and Nitrate Treatments

Frontiers in Microbiology, 2018
Sulfide biogenesis (souring) in oil reservoirs is an extensive and costly problem. Nitrate is currently used as a souring inhibitor but often requires high concentrations and yields inconsistent results.

Trends in the Exposure, Distribution, and Health Risk Assessment of Perchlorate among Crayfish in the Middle and Lower Reaches of the Yangtze River

Foods, 2022
Perchlorate is a well-known thyroid-disrupting chemical as well as an extremely stable inorganic pollutant widely distributed in the environment. Therefore, perchlorate posts potential risks to the environment as well as human health.

Occurrence of perchlorate in indoor dust from the United States and eleven other countries: Implications for human exposure

Environment International, 2015
Perchlorate is a widespread environmental contaminant and potent thyroid hormone disrupting compound. Despite this, very little is known with regard to the occurrence of this compound in indoor dust and the exposure of humans to perchlorate through dust ...

Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961
Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 ...

Transport and degradation of perchlorate in deep vadose zone: implications from direct observations during bioremediation treatment [PDF]

Hydrology and Earth System Sciences, 2017
An in situ bioremediation experiment of a deep vadose zone ( ∼  40 m) contaminated with a high concentration of perchlorate (> 25 000 mg L−1) was conducted through a full-scale field operation.

Stratospheric Gas‐Phase Production Alone Cannot Explain Observations of Atmospheric Perchlorate on Earth

Geophysical Research Letters, 2023
Perchlorate has been observed in many environments on Earth and Mars but its sources remain poorly quantified. In this study, we use a global three‐dimensional chemical transport model to simulate perchlorate's gas‐phase photochemical production ...
