Microscopic Obeservation of Chromium Deposits Surface from Low Concentration Chromium Plating Solution

Waste Minimization in Chromium Plating Industry Waste Minimization in Chromium Plating Industry

Membrane electrolysis (ME) is the only commercial technology using ion-exchange membranes for chromic acid recycling and recovery. On one hand, the technology has a number of promising advantages, but on the other hand, it has not yet gained common acceptance probably due to a lack of operation stability and efficiency. Published results of the research can be divided into three categories: lab...

Hair chromium concentration and chromium excretion in tannery workers.

Hair and urine samples were collected from 34 male tannery workers and from 12 normal adults. Eighteen of the workers dealt directly with chromium and the remaining 16 (controls) worked in the offices and kitchen of the same factory. All were found to be clinically healthy. Chromium was determined by flameless atomic absorption spectroscopy. When compared with normal adult values, urinary chrom...

Removal of Hexavalent Chromium in Vitro and from Contaminated Soils by Chromate-Resistant Fungi from Chromium Deposits

Chromium (Cr), a widespread environmental pollutant, is released from various industries including tanneries, metal cleaning and processing, chromium plating, wood processing, and alloy formation. In the developing as well as in the underdeveloped countries, the industrial effluents are released directly or indirectly into the natural water resources, mostly without proper treatment, posing a m...
