This study describes the removal of chromium from wastewater using pressure-driven membrane separation processes. It describes the rejection of trivalent chromium using a commercial membrane for reverse osmosis typed RO98pHt (Alfa Laval, Sweden). Model solutions of chromium were used for performing of separation experiments. The effects of feed pH, chromium concentration and temperature were in...

BACKGROUND Several authors, mostly on the basis of nonrandomized studies, have suggested dietary trivalent chromium supplementation as an attractive option for the management of type 2 diabetes and for glycemic control in persons at high risk of type 2 diabetes. OBJECTIVE The study aimed to determine the effect of chromium on glucose and insulin responses in healthy subjects and in individual...

This research aimed to quantify the speciation of chromium in different industrial effluent samples Hyderabad and Jamshoro, Pakistan. The hexavalent (Cr(VI)) was determined by microsample injection system flame atomic absorption spectroscopy (MIS-FAAS). total measured MIS-FAAS after oxidation trivalent (Cr(III)) Ce(SO4)2 an acidic medium (0.07 M H2SO4). content Cr(III) difference method (total ...

Golgi impregnation is unique in its ability to display the dendritic trees and axons of large numbers of individual neurons by histology. Here we apply magnetic resonance microscopy to visualize the neuroanatomy of animal models by combining histologic fixation chemistry with paramagnetic contrast agents. Although there is some differential uptake of the standard small-molecular-weight contrast...

In vitro incubation of swine adipose tissue slices in the presence or absence of insulin with a synthetic glucose tolerance factor (GTF) did not increase glucose utilization for oxidative metabolism or lipogenesis. GTF had no effect on glucose clearance rate or peak insulin response following an intravenous glucose challenge. Based on the glucose clearance rate and nominal stimulation of insuli...

Heavy metals have significant importance in altering the immune response. Chromium is found in the environment commonly in trivalent, Cr (III), and hexavalent, Cr (VI), forms. The reduction of Cr (VI) to Cr (III) results in the formation of reactive intermediates (ROS) that contribute to the cytotoxicity and genotoxicity. In this study mice were treated with chromium (VI) oxide (24 mg /kg body ...

Compared to divalent ruthenium coordination complexes, which are widely exploited as parts of multi-component photonic devices, optically active trivalent chromium complexes are under-represented in multi-metallic supramolecular architectures performing energy conversion mainly because of the tricky preparation of stable heteroleptic CrIII building blocks. We herein propose some improvements wi...
