One of heavy metal pollutants in the soil that can be absorbed by the sorghum is chromium (Cr). The study was conducted to determine the growth response of Cr3+ stress of sorghum cultivars. Two chemical compounds Cr3+ and 3 level concentrations were expos... see more

the increasing number of cases of soil contamination by trace elements have affected crop production, and represents a risk threatening the quality of our food products. Some of these contaminants, such as trivalent chromium Cr (NO3)3, which is similar to... see more

In the present study, the performance of sodium polyacrylate beads on the removal of trivalent chromium Cr (III) from aqueous solutions was evaluated using several techniques such as Fourier Transformed Infrared Spectroscopy (FTIR), Scanning Electron Micr... see more

Electrochemical behavior of different anode materials in electrolytes containing trivalent chromium salts was investigated. Some of electrodes (Ti/MnO2, platinized titanium, materials based on Ebonex®) were shown to be n-type semiconductors. Semiconductin... see more

This article presents the regularities of reduction of sulfur, nitrate and nitrite ions by sulfur reducing bacteria Desulfuromonas sp., which were isolated from the water of the man-made Yavorivske Lake (Lviv Region, Ukraine), under the influence of potas... see more

Nitrogen (N) is an important nutrient for agriculture, and Brazil is heavily dependent on N imports. A by-product of the intermediate processes of tanning (BPIPT) may be used as an N fertilizer which will reduce this dependency, but its chromium (Cr) cont... see more

The process of assimilation of Cr(VI) and Cu by chromium-resistant bacteria (Arthrobacter globiformis 151B) and the influence of high-concentration Na ions on this process have been studied. The bacteria are known for their property to assimilate the hexa... see more

Chromium (VI) is a widely used industrial chemical, extensively used in paints, metal finishes, steel including stainless steel manufacturing, alloy cast irons, chrome, and wood treatment. In nature chromium occurs in divalent, trivalent and hexavalent fo... see more

Hexavalent chromium [Cr (VI)] is a metal utilized in different industries and consequently disposed in the environment. It is a toxic substance and its reduction to trivalent Cr [Cr (III)] generates intermediates, which are responsible for the oxidation o... see more
