Oxidation-reduction equilibrium experiments were conducted with oxide melts containing CaO, Li2O, Al2O3, ZnO, B2O3, SiO2 and small concentrations of copper oxide. The results indicated that for compositions wit
NATURAL oxidation of ferrous to ferric iron by bacteria such asThiobacillus ferrooxidansorGallionella ferruginea1, or by chemical oxidation2,3has previously been thought always to involve molecular oxygen as the electron acceptor. Anoxic photochemical reactions4–6or a photobiological process involving two...
5. The ferrous metal sector was hit the hardest, with profits slumping by 57 percent. ferrous的意思ferrous 英英释义 ferrous的意思 adj 1. of or relating to or containing iron Synonym: ferric
The present invention discloses a new type of biofuel cell, based on the microbial regeneration of the oxidant, ferric ions. The bio-fuel cell is based on the cathodic reduction of ferric to ferrous ions, coupled with the microbial regeneration of ferric ions by the oxidation of ferrous ions...

3. Glass is separated by hand at the dump and ferrous metal removed by magnet .玻璃在堆放场用手拣出,黑色金属用磁铁分出。 4. Ferrous metals, timber, and pulp seem to offer the main field of reduction .看来,黑色金属、木材和纸浆是削减的重要对象。 5. Conversion of ferrous to ferric iron ...
This model represents the indirect mechanism of mineral attack by the ferric iron bound to the EPS of the A. ferrooxidans cells. As an example, chalcopyrite (CuFeS2) is shown in which ferrous iron, copper (ii), and elemental sulfur are generated upon its oxidation. SDO, sulfur dioxygenase;...
reduced activation energy induced by nanoconfinement effects for FeSO3+dissociation into sulfite radicals and for DCAA dechlorination. Meanwhile, the Fe/GO membranes give a quadruple water permeance of 48.6 L m−2h−1bar−1as GO ones, due to the adjustment of FeO NPs to oxidation degr...
Ferrous, which is different from ferric in chemistry, means iron related, especially iron with a valance of 2 (Fe++) that exists asoxidationstate (FeO).Ferrous metals, in general, refer to iron and steel materials. Steel is the major ferrous metal, an alloy of iron and carbon, and is ...
Legumes contained cryptochromic pigment is colorless upon reduction state while being oxidized into black upon oxidation in alkaline condition. Taking advantage of the reduction property of ferrous sulfate can achieve the purpose of color protection with the usage amount of 0.02% to 0.03%. ...
