提出了一种简单快速的固相分光光度法测定环境和生物样品中的游离 Fe(III)。特别是，开发了介孔二氧化硅上的去铁胺（DFO）自组装单层（DFO SAMMS），并在此用作铁（III）传感器。当与铁(III)溶液接触时，固体产物变成棕色；因此考虑立即将其应用为比色传感器。为了优化 DFO SAMMS 合成并获得铁 (III) 传感的最佳产品，进行了析因实验设计，选择 425 nm 处的最大吸收作为响应。分光光度法的稳健性也得到了证明。 (C) 2014 年沙特国王大学。由 Elsevier B.V. 制作和主持
A simple and rapid solid-phase spectrophotometric procedure to determine free Fe(III) in environmental and biological samples is proposed. In particular, a deferoxamine (DFO) self assembled monolayer on mesoporous silica (DFO SAMMS) is developed and here applied as a sensor for iron(III). The solid product became brownish when put in contact with iron(III) solutions; so an immediate application as colorimetric sensor is considered. In order to optimize the DFO SAMMS synthesis and to obtain the best product for iron(III) sensing, a factorial experimental design is performed selecting the maximum absorption at 425 nm as response. The robustness of the spectrophotometric method is also proved. (C) 2014 King Saud University. Production and hosting by Elsevier B.V.
