Diluted tributyl phosphate as an extraetant for silver

Mikrochimica Acta, 1971
A new method is devised for the rapid solvent extraction of silver with diluted tributyl phosphate. Thus 40% TBP in butanol quantitatively extracts silver (49.8μg) from 1M nitric acid that is 2M in lithium nitrate as salting-out agent. Silver is stripped with dilute ammonia and is determined photometrically at 495 ran as its red-violet complex withp ...

Calcium phosphate-encapsulated silver powder

Surface and Coatings Technology, 2009
Abstract Calcium phosphate encapsulated silver powder was obtained by heterogeneous nucleation during treatments of dispersed silver first with solutions of Ca(NO 3 ) 2 and then with Na 2 HPO 4 . Before treatment silver powders were functionalized with 3-mercaptopropionic acid and dispersed in a precipitation medium so the carboxylate groups could ...

The Crystal Structure of Silver Phosphate

The Journal of Chemical Physics, 1936
A new value for the oxygen parameter in the structure of silver phosphate has been determined which gives the P–O separation in the phosphate group as 1.61A±0.03A. The value found here is slightly larger than that determined from an analysis of the crystal KH2PO4.

The behaviour of silver phosphate as the electroactive sensor in a phosphate-sensitive electrode

Analytica Chimica Acta, 1976
Abstract A phosphate ion-selective electrode based on silver phosphate as the electroactive material is described. The behaviour of the electrode is Nernstian, the response time is 2 min, the detection limit is 10-5 M total phosphate, and the short-term stability is within 0.5 mV.

Neutron Response of Silver-activated Phosphate Glass

Health Physics, 1960
The fluorescent response of silver-activated phosphate glass rods exposed to thermal and 14 MeV neutrons has been investigated. For thermal neutrons most of the absorbed dose in this glass arises from beta-emission of activated silver nuclei, and the response per rad in this glass is the same as for Co60 gamma-rays. For 14 MeV neutrons the response per

Silver dynamics in silver iodide/silver phosphate glasses studied by multi-dimensional 109Ag NMR

Physical Chemistry Chemical Physics, 2002
Various 109Ag NMR techniques are used to study silver diffusion in silver iodide/silver phosphate glasses. In particular, for the first time, four-dimensional (4D) NMR is applied on solid ion conductors. All experiments consistently show that silver dynamics are governed by a very broad, continuous distribution of correlation times G(lg τ). First, over

Silver-doped calcium phosphate cements with antimicrobial activity

Acta Biomaterialia, 2011
There is a current need for the localised delivery of antibiotics in order to treat implant-based bacterial infections. Existing treatments use non-resorbable materials such as poly(methyl methacrylate) beads loaded with antibiotics; unfortunately, as they are not resorbable, these beads require secondary surgery for removal.

Temperature behaviour of quasielastic scattering in silver phosphate glass

Philosophical Magazine B, 2002
Abstract In this work we have studied the dynamics of the silver phosphate glass AgPO3 by Raman and Brillouin light scattering experiments. This system is of interest because it is easy to study the dynamic changes in a wide range of temperatures having a glass transition temperature at about 170°C.
