as inhibitor agent of bacterial activity and growth until a certain level is well defined [22]. The dynamic interactions of ferric and ferrous iron, which form the total iron as observed in Figs. 6(a) and (b... mesophilic biomass consortium at 33.3 °C and ferric leaching process were attempted. Bioleaching experiments were settled with a fraction size of -75+53 μm. Bacteria were used as the catalyst......
absorption spectra of iron sulfate and sodium formate solution 由图3可知,硫酸铬,硫酸铁混合溶液与甲酸钠混合后的紫外吸收谱在波长409 nm附近出现一个强吸收峰,该吸收峰的出现证明硫酸铬,硫酸铁混合溶液对紫外和可见光吸收的能力发生改变.由于其与硫酸铁与甲酸钠络合的特征吸收峰比较一致,说明在混合体系中主要是铁发生了络合,即铁优先于铬与甲酸钠发生络合作用... between chromium sulfate and ferric sulfate mixed solution with sodium formate 2.2 高能质谱法对铁,铬离子与甲酸钠配位研究 对2.1节中单一硫酸铁与甲酸钠反应的溶液进行质谱分析,结果如图4所示. 由图4可知,单一的纯硫酸铁溶液与甲酸钠反应的产物,得到单一的分子离子峰,m/z的比值为229.8391,而理论产物Fe......
