交变磁场对聚合硫酸铁水解产物的影响

Influences of alternative magnetic fields on the hydrolysis product polymeric ferric sulfate(PFS)

电镜扫描分析,交变磁场下聚合硫酸铁晶体颗粒尺寸明显比非磁化PFS要大,应该是由于磁结晶效应。采用红外光谱、X射线衍射,确定了磁化作用并没有使PFS形成新羟基键化合物,排除其结构上的差异。而通过紫外光谱分析发现,磁化作用使Fe(c)含量减小,推断在交变磁场作用下,使得Fe3+水合离子化合物的束缚力增强,抑制Fe3+进一步生成Fe(c)这类高聚态化合物,从而使Fe(a)、Fe(b)这类低聚态铁离子水合化合物含量增多。

It is characterized by SEM analysis that the crystal granular size of polymeric ferric sulfate （PFS） under the action of alternative magnetic field is obviously larger than that of non-magnetized PFS. It should be magnetic crystallization effect. It is determined by FTIR and XRD methods that the magnetization does not make PFS form any new hydroxy bond compounds,and the difference in structures is excluded. According to UV analysis,the crystallization action makes the Fe （c） content decrease. It is deduced that under the action of alternative magnetic field, the binding power of Fe^3＋ hydrated ion compounds is enhanced,inhibiting Fe^3＋ to further form such a kind of high polymeric compounds Fe （c）, so as to make the contents of such kinds of low polymeric iron ion hydrated com- pounds, Fe （a） and Fe （b） increase.
