2019/12/2
A new study that combines measurements from some 1,400 drinking water wells across North Carolina estimates that more than half the wells in the state's central region contain levels of cancer-causing...
Chromium-Containing Organic Fertilizers from Tanned Hides and Skins: A Review on Chemical, Environmental, Agronomical and Legislative Aspects
Organic Fertilizers Tanned Hides and Skins Hydrolyzed Leather Trivalent Chromium Hexavalent Chromium Soil
2013/3/12
A category of chromium (Cr)-containing fertilizers is represented by the fertilizers deriving from byproducts of tanning process. Their use is widespread because of their good agronomic response due t...
Evaluation of the Adsorption of Hexavalent Chromium on Kaolinite and Illite
Hexavalent Chromium Clay Mineral Sediment Adsorption Stabilization
2013/3/13
The adsorption of hexavalent chromium on Kaolinite and Illite was studied in order to evaluate their potential for the reduction of hexavalent chromium mobility and their possible application for the ...
Studies on Chromate Removal by Chromium-Resistant Bacillus sp. Isolated from Tannery Effluent
Bacillus sp. Bioremediation Cr (VI) Removal Tannery Effluent
2013/3/12
A chromate-removing strain was isolated from spent chrome effluent and identified as Bacillus circulans strain MN1. The isolated strain was studied for resistance to Cr (VI) and its ability to remove ...
