Environmental Aspects and Controlling Cr⁶⁺ Emissions of Chromium Electroplating

Preliminary Assessment of Chromium Emissions from Chromium Electroplating Faci Lities

The United States Environmental Protection Agency (EPA) intends to add either chromium or hexavalent chromium to the list of hazardous air pollutants under Section 112 of the Clean Air Act. A preliminary assessment performed by EPA has identified several categories of stationary sources as emitters of significant quantities of chromium to the atmosphere and for which the proposal o f national e...

Extraction and recovery of chromium from electroplating sludge.

This work reports a study of the extraction and recovery of chromium from the wastes (class I dangerous) generated by a galvanic manufacturer. Commercial HCl at room temperature was employed, and the conditions of the extraction process were optimized according to a sequential experimental design, which also included the acid concentration and contact time as variables. The best extraction cond...

A New Method for Electroplating of Crack-Free Chromium Coatings

In this study, different amounts of MoS2 particles and an anionic surfactant were added to the conventional chromium electroplating bath in order to electrodeposite crack-free chromium coatings and the structure, morphology, tribology and corrosion behavior of the deposited coatings were investigated using X-ray diffraction spectroscopy, scanning electron microscopy, pin on disk ...

Effect of Chromium on Certain Aspects of Cellular Toxicity

Introduction: The impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male Wistar rats (80-100 g body weight). Material & Method: It was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight a...
