Qualities of electrodeposited zinc from cyanide, sulfate and chloride bath

Preparation and Characterization of Electrodeposited Iron + Cobalt Thin Films from a Chloride Bath

Ligas Fe-Co foram depositadas e dissolvidas em solução contendo íons metálicos e em solução de NH 4 Cl. Resultados voltamétricos sugerem interação entre os componentes da liga, originando uma solução sólida. Perfis de ALSV apresentam diferenciação para o processo de dissolução dos metais individuais e das ligas, com comportamento semelhante ao observado para cobalto e/ou ferro, com deslocamento...

Acute Toxicity of Mercuric Chloride (HgCl2), Lead Chloride (PbCl2) and Zinc Sulfate (ZnSO4) on Silver Dollar Fish (Metynnis fasciatus)

Background: Since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. The aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of Mercuric Chloride (HgCl2), Lead Chloride (PbCl2) and Zinc Sulfate (ZnSO4) pollutan...

Mirror-Bright Silver Plating from a Cyanide-Free Bath

ilver has good electric conductivity and solderability and possesses S excellent electric characteristics as a contact and is thus widely used for plating electronic industrial parts. A cyanide plating bath is most often used, but the cyanide compounds have strong toxicity and a large amount of the cost is rxpkd for securing safe working conditions and waste treatment. Because of this, many cya...

Effect of zinc sulfate and sodium chloride stress on two rootstocks of Qazvini and Badami Zarand pistachio in greenhouse conditions

ELECTRODEPOSITION OF Ni-Fe ALLOYS FROM SULFATE, SULFATE-CHLORIDE AND CHLORIDE BATHS

In an attempt to control the film composition, factors affecting the composition of Ni-Fe alloy deposits and their crystal structure have been analyzed as a function of bath composition, cathode current density, bath pH, temperature and an addition of citric acid. antimony electrode revealed that the deposition potential of Fe coincides with the potential where the abrupt increase of pH was obs...
