含 Fe( )的溶液具有很强的缓冲能力 ,并且可用于原水的混凝处理上 ,使胶体离子脱稳、聚合 ,使水澄清。铁是过渡金属 ,有强烈的水解倾向。其 3价离子共有 6个空轨道 ,可与 OH-形成单核、双核、多核络合物。为了探讨铁离子的水解和聚合形态 ,取 Fe3 +浓度在 0 .1 mol/L以下的 3个不同浓度的溶液 ,用 Na OH标准溶液进行碱滴定 ,画出滴定曲线 ,根据滴定曲线的形状 ,分析铁的水解和聚合。 Fe () containing solution has a strong buffering capacity, and can be used for coagulation of raw water, the colloidal ions destabilization, polymerization, the water clarified. Iron is a transition metal with a strong tendency to hydrolyze. The trivalent ions have a total of six empty orbitals that form mononuclear, binuclear and polynuclear complexes with OH-. In order to investigate the hydrolysis and polymerization of ferric ions, three different concentrations of solutions with Fe3 + concentrations below 0.1 mol / L were alkalimerized with NaOH standard solution and the titration curve was drawn. According to the shape of the titration curves, Analysis of iron hydrolysis and polymerization.
