Indirect atomic-absorption spectrophotometric determination of phosphorus in steel by use of the bismuth phosphomolybdate complex

Talanta, 1988
An indirect method for determination of phosphorus by atomic-absorption spectrophotometry has been developed, based on formation of the bismuthophosphomolybdate complex and its extraction by methyl isobutyl ketone. Bismuth is determined in the extract and correlated with the phosphorus content. The method is applicable to different kinds of steel.

Atomic absorption spectrometric method for the determination of phosphorus using the bismuth-phosphomolybdate complex

Journal of Analytical Atomic Spectrometry, 1987
An improved method for the determination of micro-amounts of phosphorus by atomic absorption spectrometry is described. This technique is not generally applied to the determination of non-metals as their resonance lines fall in the ultraviolet region where atmospheric absorption is a problem.

Indirect atomic absorption spectrometric determination of phosphorus in high purity electronic grade silicon using bismuth phosphomolybdate complex

Microchemical Journal, 1991
Abstract Phosphorus plays a key role in the fabrication of silicon-based electronic devices. The determination of phosphorus in silicon has been carried out by atomic absorption spectroscopy (AAS) using a bismuth phosphomolybdate complex. Bismuth and phosphorus are present in the stoichiometric ratio of 1:1 in the complex.

Visible-Light-Driven Hydrogen Peroxide Synthesis by a Hybrid Photocatalyst Consisting of Bismuth Vanadate and Bis(hexafluoroacetylacetonato)copper(II) Complex

, 2020
The adsorption of bis(acetylacetonato)Cu(II) on monoclinic scheelite bismuth vanadate forms an O2-bridged dimer complex on the surface resembling hemocyanin in the biosystems (Cu(acac)2/ms-BiVO4).

Synthesis, Properties, and Complex Formation of Antimony- and Bismuth-Bridged Bipyridyls

Organometallics, 2019
Antimony- and bismuth-bridged bipyridyls (dipyridinostibole and dipyridinobismole; DPySb and DPyBi) were prepared by the reactions of dilithiobipyridyl with dibromophenylstibine and diiodophenylbismuthine.

A tunable room-temperature nonlinear Hall effect in elemental bismuth thin films

Nature Electronics, 2023
The nonlinear Hall effect with time-reversal symmetry is a second-order electronic transport phenomenon—seen as a quadratic voltage transverse to an applied electric field—that induces frequency doubling and occurs in non-centrosymmetric crystals with ...
