Synthesis and characterization of defective UiO-66 for efficient co-immobilization of arsenate and fluoride from single/binary solutions.

Environmental Pollution, 2021
Here, we aimed to synthesize UiO-66 architected fumaric acid mediated lanthanum (La-fum), zirconium (Zr-fum), and cerium (Ce-fum) metal-organic frameworks (MOFs) for co-immobilizations of both arsenate and fluoride from both single and binary systems ...

Two new arsenate/sulfate-reducing bacteria: mechanisms of arsenate reduction

Archives of Microbiology, 2000
Two sulfate-reducing bacteria, which also reduce arsenate, were isolated; both organisms oxidized lactate incompletely to acetate. When using lactate as the electron donor, one of these organisms, Desulfomicrobium strain Ben-RB, rapidly reduced (doubling

Uptake, accumulation and translocation of arsenate in arsenate-tolerant and non-tolerant Holcus lanatus L.

New Phytologist, 1991
Uptake, translocation and accumulation of arsenate was determined in arsenate‐tolerant and non‐tolerant genotypes of Holcus lanatus L. Over a 6 h period of growth in 005 mol m−3arsenate, non‐tolerant genotypes accumulated arsenate to a much greater ...

Three-dimensional flower-like multifunctional adsorbents with excellent sorptive removal and colorimetric detection of arsenate

Chemical Engineering Journal, 2020
It is highly desirable to construct advanced adsorbents with superb adsorption and visual detectivity of arsenate from complex environmental systems. In this work, a novel kind of iron alkoxide for simultaneous sorptive removal and colorimetric detection

Mechanisms of arsenate tolerance in Cytisus striatus

New Phytologist, 2003
Arsenate tolerance, uptake and arsenate-induced phytochelatin (PC) accumulation were compared at different phosphorus supply rates in two populations of the broom, Cytisus striatus, one from an arsenic-enriched gold mine and one from a nonmetalliferous ...

The Role of extracellular polymeric substances (EPS) in microbial reduction of arsenate to arsenite by Escherichia coli and Bacillus subtilis.

Environmental Science and Technology, 2020
We show that arsenate can be readily reduced to arsenite on cell surfaces of common bacteria (E. coli or B. subtilis) or in aqueous dissolved EPS extracted from different microorganisms (E. coli, B. subtilis, P. chrysosporium, D.

Development of Eu-based metal-organic frameworks (MOFs) for luminescence sensing and entrapping of arsenate ion

, 2021
A new type of Eu-based metal organic framework (Eu-MOF) characterized with ability of arsenate ion luminescence sensing and entrapping was constructed via solvothermal method based on the optimization of the organic ligand.

The Determination of Arsenic in Official Arsenicals*†

Journal of the American Pharmaceutical Association (Scientific ed.), 1947
Abstract An assay for the determination of arsenic is presented which is applicable to six of the seven Pharmacopoeial arsenicals. The method employs an alkali‐acid permanganate oxidation for the destruction of organic matter.

Direct epitaxial synthesis of magnetic Fe3O4@UiO-66 composite for efficient removal of arsenate from water

Microporous and Mesoporous Materials, 2019
Facile fabrication of magnetic metal-organic frameworks (MOFs) using a direct epitaxial approach for eliminating arsenic from water is highly desirable. Herein, a two-step solvothermal method of elegant design is proposed to synthesize Fe3O4@UiO-66. Such

Efficient arsenate reduction in As-hyperaccumulator Pteris vittata are mediated by novel arsenate reductases PvHAC1 and PvHAC2.

Journal of Hazardous Materials, 2020
Arsenic-hyperaccumulator Pteris vittata is efficient in As absorption, reduction, and translocation. But the molecular mechanisms and locations of arsenate (AsV) reduction in P. vittata are still unclear.
