For the removal of iron(III), Sepharose-desferrioxamine gels were prepared by the coupling of CNBr-activated Sepharose with desferrioxamine (DFO) at pH 7.8-8.3. DFO densities of the gels were 12-23 mumol/ml gel with iron(III) chelating capacities of 8.5-18 mumol/ml gel. The Sepharose-DFO gels with a high affinity for iron(III) were used for the removal of iron(III) from aqueous iron(III) solutions, wine, milk and whey.
为了去除铁（III），通过在pH 7.8 - 8.3的条件下将溴化氰活化的琼脂糖与去铁胺（DFO）偶联来制备琼脂糖 - 去铁胺凝胶。凝胶的DFO密度为12 - 23 μmol/ml凝胶，铁（III）螯合能力为8.5 - 18 μmol/ml凝胶。对铁（III）具有高亲和力的琼脂糖 - DFO凝胶用于从铁（III）水溶液、葡萄酒、牛奶和乳清中去除铁（III）。
