  Some industrial processes, such as plating and gold mining, utilize cyanide, which entering in their effluents. Because cyanide compounds are toxic contaminants, the waste-containing cyanide must be treated before discharge in the environment. Several methods are available for cyanide removal or detoxification. Natural degradation, alkaline chlorination, and oxidation with hydrogen peroxide a...

Herein we demonstrate a novel plating bath, free from cyanide, to plate highly adherent nanocrystalline copper-silver (ncCuAg) coating on stainless-steel substrate and its application as an antimicrobial coating. The microstructures, such the grain size, texture, microstrain, crystalline preferential orientation of CuAg deposits, are systematically investigated by X-ray diffraction analysis. ra...

The role of thiourea as an organic additive in the nucleation and growth mechanism was studied for copper deposition its application decorative electroplating fashion accessory industries. bath designed to reduce environmental ecological impacts using methanesulfonic acid electrolyte alternative alkaline cyanide baths. We evaluated exploiting voltametric chronoamperometric measurements with a b...

We determined relationships between oxygen uptake and mechanical tension in isolated strips of rabbit aorta treated with various agonists; organ bath Poi was varied over the range 4-350 mm Hg, or cyanide (CN) was added to the organ bath in concentrations of from 8 x 10"' to 3 x 10" M. Oxygen tension-dependent mechanical tension changes were similar during contractions caused by norepinephrine a...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...

Phytoremediation counts as a major method for future which essentially needs resistance to contaminating agents. We pretreated the plants (Salix babylonica, as a model plant in phytoremediation of polluted waters) by sodium cyanide (0, 3 and 5 mg CN- L-1) to induce resistance with regard to acclimation and then examined their resistance to higher concentrations of cyanide. Accordingly, some of ...

samples of the waste rock obtained from marofengin south africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. the results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, 70 a...
