objective high concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. however, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. materials and methods in a series of experiments, bucillus cereus was cultured in a n...

Cr(VI) is an important contaminant found at sites where chromium ore processing residue (COPR) is deposited. No low cost treatment exists for Cr(VI) leaching from such sites. This study investigated the mechanism of interaction of alkaline Cr(VI)-containing leachate with an Fe(II)-containing organic matter rich soil beneath the waste. The soil currently contains 0.8% Cr, shown to be present as ...

• Cr(VI) removal by iron-biochar (Fe-BC) was evaluated machine learning. Direct impact of impregnated-Fe content on limited. Indirect impacts Fe were critical due to variable Fe-BC properties. Impregnated-Fe improved SOFGs contents for removal. C−O more than C=O Data mining and knowledge discovery learning (ML) have recently come into application in environmental remediation, especially the exp...
