Perchlorate and chlorate assessment in drinking water in northern Chilean cities.

Environmental Research, 2023
Perchlorate and chlorate are endocrine disruptors considered emerging contaminants (ECs). Both oxyanions are commonly associated with anthropogenic contamination from fertilizers, pesticides, explosives, and disinfection byproducts. However, the soils of

Exploring cell aggregation as a defense strategy against perchlorate stress in Chlamydomonas reinhardtii through multi-omics analysis.

Science of the Total Environment, 2023
Perchlorate (ClO4-) is a type of novel, widely distributed, and persistent inorganic pollutant. However, the impacts of perchlorate on freshwater algae remain unclear.

Formation of anaerobic granular sludge (AnGS) to treat high-strength perchlorate wastewater via anaerobic baffled reactor (ABR) system: Electron transfer characteristic, bacterial community and positive feedback mechanism.

Science of the Total Environment, 2022
Anaerobic granular sludge (AnGS) was cultured to treat high-strength perchlorate (reaching to 4800 mg/L) wastewater by an anaerobic baffled reactor (ABR) system with five equal-volume compartments (C1-C5 compartments).

Monitoring contamination of perchlorate migrating along the food chain to dairy products poses risks to human health.

Food Chemistry, 2021
Assessments of human exposure to sodium perchlorate via dairy sources are limited. The current study applied untargeted metabolomics (LOD, 1.08-35.60 μg L-1; LOQ, 2.54-90.58 μg L-1; RSD

N-doped activated carbon with hierarchical pores for the efficient removal of perchlorate from water

Microporous and Mesoporous Materials, 2021
Perchlorate contamination in drinking water is causing serious health issues. N-doped activated carbon with hierarchical pore structure having very high perchlorate adsorption capacity was synthesized from polypyrrole using Pluronic 123 as a template ...

Perchlorate in Milk

Environmental Science & Technology, 2003
Perchlorate was unambiguously detected by ion chromatography-suppressed conductivity (IC-CD) and/or ion chromatography-electrospray mass spectrometry (IC-MS) in seven of seven supermarket milk samples bought randomly in Lubbock, TX. Quantitation by IC-MS and IC-suppressed conductivity detection in conjunction with a preconcentration-preelution method ...

Exploiting a perchlorate-tolerant desert cyanobacterium to support bacterial growth for in situ resource utilization on Mars

International Journal of Astrobiology, 2020
The presence of perchlorate in the Martian soil may limit in-situ resource utilization (ISRU) technologies to support human outposts. In order to exploit the desiccation, radiation-tolerant cyanobacterium Chroococcidopsis in Biological Life Support ...

Perchloric acid in the synthesis of covalent perchlorates

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1977
1. The authors have investigated the conditions of hydration of multivalent metal ions by perchloric acid; hydration does not occur in acid containing oxonium perchlorate. Transfer of water from perchloric acid to the ion being hydrated proceeds via a stage of formation of oxonium perchlorate by equilibrial auto-dehydration. 2.

Enhanced the combustion performances of ammonium perchlorate-based energetic molecular perovskite using functionalized graphene

Vacuum, 2019
Ammonium perchlorate-based molecular perovskite (DAP)/graphene energetic composite was prepared and characterized. Molecule perovskite DAP was synthesized by the one-pot reaction of ammonium perchlorate, perchloric acid, and triethylenediamine, and DAP ...
