Zinc recovery and waste sludge minimization from chromium passivation baths.
This work reports the feasibility of applying emulsion pertraction technology (EPT) aiming at zinc recovery and waste minimization in the zinc electroplating processes that include Cr (III) passivation. The assessment consists of firstly the lifetime extension of the passivation baths by selective removal of the tramp ions zinc and iron, and secondly, the recovery of zinc for further reuse. Spe...
متن کاملElectrodeposition and Characterization of Sn-Zn Alloy Coatings from Sulfate Based Baths
Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...
متن کاملELECTRODEPOSITION 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...
متن کاملFoot infections in swimming baths.
A 10% random sample of all bathers at a public swimming bath were examined for tinea pedis and verruca.The overall incidence of tinea pedis was 8.5% and of verruca 4.8%. The incidence of tinea pedis in 205 male adults was 21.5%, in 288 boys 6.3%, in 60 adult females 3.3%, and in 220 girls 0.9%. The incidence of verruca in juveniles ranged from 4.2% in boys to 10.5% in girls.It was clear that bo...
متن کاملAvian Assemblages at Bird Baths: A Comparison of Urban and Rural Bird Baths in Australia
Private gardens provide habitat and resources for many birds living in human-dominated landscapes. While wild bird feeding is recognised as one of the most popular forms of human-wildlife interaction, almost nothing is known about the use of bird baths. This citizen science initiative explores avian assemblages at bird baths in private gardens in south-eastern Australia and how this differs wit...
