Silver toxicity is a problem that microorganisms face in medical and environmental settings. Through exposure to silver compounds, some bacteria have adapted to growth in high concentrations of silver ions. Such adapted microbes may be dangerous as pathogens but, alternatively, could be potentially useful in nanomaterial-manufacturing applications. While naturally adapted isolates typically uti...

Silver is used widely in wound dressings and medical devices as a broad-spectrum antibiotic. Metallic silver and most inorganic silver compounds ionise in moisture, body fluids, and secretions to release biologically active Ag(+). The ion is absorbed into the systemic circulation from the diet and drinking water, by inhalation and through intraparenteral administration. Percutaneous absorption ...

A novel technique for silver extraction from Ag2S is described. The method utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved. The parameters of the reaction such as pH, the reaction temperature, the complex equilibrium of Ag ion with thiosulphate and the solubility of Ag2S were investigated. Silver ions, obtained by this me...

heavy metals removal from polluted wastewater is one of the major concerns due to their harmful effectson human health and the environment. the aim of this study is to absorb cu2+ and co+2 ions from wastewater by means of a synthesized magnetite bentonite nono - adsorbent. initially, nano- adsorbent was produced by coprecipitation techniques. then, the resultant material was analyzed and evalua...

BACKGROUND Tumor patients and patients after traumas are endangered by a reduced immune defense, and a silver coating on their megaprostheses may reduce their risks of infection. The aim of this study was to determine the silver ion concentration directly measured from the periprosthetic tissue and the influence on the clinical outcome. MATERIAL AND METHODS Silver ions were evaluated in 5 mL ...

The ion dynamics of silver ablated using 355 and 193nm pulsed laser irradiation in vacuum has been investigated by using a Langmuir probe and quadrupole mass spectrometry. The kinetic energies of the ablated silver ions were measured to be between 5 and 40 eV depending on the laser fluence. In addition, the angular distributions of ablated species showed that ionic species are preferentially ej...

some biochemical properties of silver carp surimi prepared by application of acid-alkali aided methods were investigated and compared to that of derived by conventional method. in terms of total protein solubility and recovery, lipid reduction, and total pigment extractability and myoglobin removal there was a significant (p

A convenient reference cell and method of potentiometric determination of chloride ions with silver nitrate is described. The method is accurate to about +/- 0.02 ml. 10(-4)M silver nitrate.
