GFAJ-1 is an arsenate-resistant, phosphate-dependent organism

, 2012
The bacterial isolate GFAJ-1 has been proposed to substitute arsenic for phosphorus to sustain growth. We have shown that GFAJ-1 is able to grow at low phosphate concentrations (1.7 muM), even in the presence of high concentrations of arsenate (40 mM ...

Effect of competing anions on arsenate adsorption onto maghemite nanoparticles

, 2012
This paper reports the effect of several competing anions on arsenate adsorption with maghemite nanoparticles. Sulphate (as SO 4), nitrate (as NO 3-N), phosphate (as PO 4-P) ions and silicate (as SiO 2) were studied in dual solution with arsenate ...

Optimized removal of arsenate(III) by adaptation of oxidation and precipitation processes to the filtration step

, 1996
Processes for the removal of arsenic from water have been widely studied. Realizable and reliable concepts, however, exist only for the removal of inorganic arsenate(V).

The molecular basis of phosphate discrimination in arsenate-rich environments

, 2012
Arsenate and phosphate are abundant on Earth and have striking similarities: nearly identical pK(a) values, similarly charged oxygen atoms, and thermochemical radii that differ by only 4% (ref. 3).

THE LIGHT SCATTERING BEHAVIOUR OF THORIUM ARSENATE GEL-FORMING SYSTEMS

, 1958
The changes in the depolarisation and the intesity of transversely scattered light and opacity of thorium arsenate gels, obtained by diluting acid solution of thorium arsenate, have been investigated.
