Chromium, especially chromium (VI), is the main pollutant of the tannery and electroplating industries. Cr (VI) is said to be a hazardous pollutant as it is highly toxic, mutagenic as well a carcinogen. Cr (VI) is mobile as it is soluble in nature. In our present study, indigenous bacteria that are tolerant to high concentrations of Cr (VI) were isolated from chromium contaminated electroplatin...

Infection-related complications have been a critical issue for the application of titanium orthopedic implants. The use of Ag nanoparticles offers a potential approach to incorporate antimicrobial properties into the titanium implants. In this work, a novel and simple method was developed for synthesis of Ag (II) oxide deposited TiO2 nanotubes (TiNTs) using electrochemical anodization followed ...

Polyethylene glycol (PEG) used as a brightening and stabilization agent at the concentration of 30 mg dm(-3) is a major organic additive in the copper electroplating solution. Activated carbon, Calgon Filtrasob 400, is used as the adsorbent to remove the PEG from the used electroplating solution in order to broaden the appeal of recycling it. The equilibrium of adsorption is attained within 14 ...

Abstract Electroplated micropore interconnection is one of the core technologies to realize electronic connections high-density multilayer Printed circuit board (PCB). The quality electroplated copper layer a key factor for reliability PCB and components. Focusing on acid plating process, this paper expounds development electroplating solution additives, mechanisms deposition hole filling mecha...

In the manufacture of zinc oxide the raw material normally used is zinc metal plates. In a factory in which old aeroplane batteries containing zinc mercury amalgam were substituted, it was not realized that mercury vapour was being produced. Of 25 workers exposed, seven developed serious chronic mercury poisoning and were admitted to hospital. The clinical findings in the affected workers are d...

Cu-Zn alloys have been electrodeposited from a pyrophosphate electrolyte containing Cu2P207> Zn2P207 salts and an excess of K4P2O7 and KN03. Current-potential data for both copper and zinc, as well their plating current efficiencies were determined from electrochemical polarisation experiments. Copper deposition commenced at potentials below -0.208 V whereas zinc was deposited only below -1.157...

Different ZnO nanostructured films were electrochemically grown, using an aqueous solution based on ZnCl2, on three types of transparent conductive oxides grow on commercial ITO (In2O3:Sn)-covered glass substrates: (1) ZnO prepared by spin coating, (2) ZnO prepared by direct current magnetron sputtering, and (3) commercial ITO-covered glass substrates. Although thin, these primary oxide layers ...

Acrylonitrile-butadiene-styrene (ABS plastic) is one of the most widely used thermoplastic resins for electroplating. In electroplating, a glossing metallic layer coated on ABS plastic surface. Yet, electroplated coating has poor adhesion to plastics. Thus, polymer producers strive develop more adhesive electroplating grades plastic. Unfortunately, there no reliable method quantify chemistry-in...
