1) First of all, divide an equation into two half-reactions such as oxidation and reduction reaction. 2) Balance two half-reactions separately. 3) First balance atoms other than O and H 4) Then balance O by adding {eq}H_2O {/eq} molecule on that side o...
Chromium in compounds can exist in various oxidation states, ranging from II to VI. In particular, chromium(VI) in CrO4~(2-) or CrO7~(2-) is highly cytotoxic substance and a potential carcinogen. A number of treatment methods for the removal of toxic heavy metal ions in water have ...
A number of techniques were used to characterize physicochemical properties of the materials, and their catalytic activities were evaluated for the oxidation of trichloroethylene (TCE). These samples possessed a good-quality 3DOM structure and a surface area of 3547 m /g. The 3DOM 5.5Cr 2 O 3...
