Due to the high toxicity of cyanide researchers are trying to find an environmentally friendly and sustainable leaching process for precious metals Thiosulfate is considered one of the most promising alternative leaching systems Nevertheless a traditional thiosulfate leaching solution generally consists of copper sulfate and ammonia in which copper
Silver sulfide Ag 2 S is a p type semiconductor material with a band gap of about 1 eV Due to its narrow band gap and large absorption coefficient in the entire solar spectrum it has received extensive attention as a photocatalyst or photosensitizer under visible and NIR irradiation [31] [32] [33] The excellent chemical stability and optical properties of Ag 2
Silver nanomaterials AgNMs are released into sewers and consequently find their way to sewage treatment plants STPs The AgNMs are transformed en route mainly into silver sulfide Ag 2 S which is only sparingly soluble in water and therefore potentially less harmful than the original AgNMs Here we investigated the toxicity and fate of different

the growth of silver sulfide Several sizes of standard thick film resistors with a variety of conformal coatings to mitigate silver sulfide corrosion were exposed to Flowers of Sulfur FoS testing at three test temperatures 60oC 80oC and 105oC to determine an acceleration factor for the resulting silver corrosion
silver sulfide leaching with respect to copper sulfate tartrate and thiosulfate concentrations in copper sulfate tartrate thiosulfate solutions are and respectively A detailed dissolution route of Ag 2S was proposed based on XRD analysis of intermediate products such as Ag 3CuS 2
Most silver based photocatalysts are narrow bandgap semiconductors that have bandgaps less than eV and can be driven by visible light except AgCl Ag 2 SO 3 Ag 2 MoO 4 and Ag 2 WO 4 and thus have been widely band structures of some common silver based compounds are listed in Fig bandgap affects the ability of a catalyst to
Silver either in ionic or nanoparticulate form is widely used in consumer products However silver sulfide Ag 2 S are more likely to be the form that Ag enters the environment The retention of silver sulfide nanoparticles Ag 2 S NPs in natural soils is critical for bioavailability and toxicity but remains unclear Here we examined the retention of Ag 2 S NPs
Abstract Transparent semiconducting silver sulfide Ag2S thin films were deposited by chemical bath deposition technique on glass substrates The effect of different deposition temperatures 10 20 and 30°C on the structural and optical properties of silver sulfide films was studied The XRD spectra showed that the structure of the films was monoclinic and
Silver tarnishes due to a natural chemical reaction with sulfur containing compounds in the air water or certain substances The main factors contributing to the tarnishing of silver include Reaction with Sulfur Compounds Silver reacts with sulfur compounds such as hydrogen sulfide H2S or sulfur dioxide SO2 w
The use of biosolids as fertilizers in agriculture can lead to the exposure of soil biota to sulfidised silver nanoparticles Ag 2 S NPs generated during the wastewater treatment procedures Considering the crucial role of microorganisms on soil functions we aimed to study the effects of 10 mg kg −1 soil of Ag 2 S NPs or AgNO 3 on the soil microbiome using an
