Reduction of Cr (VI)

Uniform and magnetic recyclable hollowsphere Zn doped Fe3O4 were successfully synthesized via simple one-pot solvothermal route. Morphology and structure of as-obtained products was characterized by XRD, SEM, HRTEM methods. The Zn-doped Fe3O4 hollowsphere exhibited high photocatalytic activity for degradation of hexavalent chromium under visible light irradiation.

The results show that the sulfur source plays a crucial role in determining the product morphology. Photocatalysis experiments show Bi2S3 nanowires exhibit the highest photocatalytic reduction of Cr(VI) when exposed to visible light irradiation.

The present study was envisaged with the objective to isolate indigenous chromate tolerant bacteria from effluents and their subsequent utilization for chromium uptake or reduction. Samples were collected from two different Common Effluent Treatment Plants (CETPs), located in Ludhiana (sample 1) and Jalandhar (sample 2). In both the samples, chromium was found to be the dominant metal contaminant. A total of 10 morphologically distinct isolates were tested for their tolerance to chromium in terms of minimum inhibitory concentration (MIC) of Cr required for complete inhibition of growth.
