resistance for the As3+ and As5+ and converting conditions from As3+ to As5+ were analyzed. The additive was used to prompt the bacterial leaching efficiency by changing valence state of arsenic... researches are emphasized on the valence state distribution of arsenic in the bacterial leaching process, bacterial resistance for As3+ and As5+, transitional conditions from As3+ to As5+ and oxidant......
the magnetostriction[12, 13]. In our previous work, the heavy rare earth Tb and Dy substitution for Ce in CexR1-xFe2 compounds result in the valence fluctuation of Ce ions towards localized state[14..., with the increasing Ce content, the Ce4f electrons in CexTb1-xFe2 compounds drift towards localized state[15], while drift towards delocalized state in PrxCe1-xFe compounds[3]. In this work, the valence of Ce ions......
