Quantitative evaluations of the uptake of an acid ferric hydroxide sol revealed the iron binding of model substrates unrelated to their ion binding capacity. Electron microscopy showed iron particles bound exclusively or mainly to the surfaces of model substrates. Morphometric estimations resulted in a good agreement of the surface/volume ratio with the amount of bound iron. The results are discussed with regard to the steric hindrance of the colloidal iron reaction resulting in a nonstoichiometric interaction.
对酸性氢氧化铁溶胶摄取量的定量评估显示，模型底物的铁结合与其离子结合能力无关。电子显微镜显示铁颗粒仅或主要结合在模型底物的表面。形态测量估计得出表面/体积比与结合铁量之间具有良好的一致性。针对胶体铁反应的空间位阻导致非化学计量相互作用这一情况对结果进行了讨论。
