2023年8月29日 · Characteristics: Iron is a gray, moderately active metal. The [Fe(H2O)6]3+ [Fe (H 2 O) 6] 3 + ion is colorless (or pale pink), but many solutions containing this ion are yellow or amber-colored because of hydrolysis. Iron in both oxidation states forms many complex ions.

2024年5月1日 · In this study, we report an innovative Fe detection strategy by using both a ligand probe and an engineered nanopore with two binding sites. In our design, one binding site of the nanopore has a strong interaction with the ligand probe, while the other is more selective toward interfering species.

For the Fe3+ ion we remove a total of three electrons (two from the 4s2 and one form the 3d6) leaving us with 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 1s2 2s2 2p6 3s2 3p6 3d5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

2025年2月1日 · Achieving low-cost, high-efficiency quantification of Fe 3+ ion concentration in unknown solutions can guide environmental management decisions and optimize water treatment processes.

铁离子（ferri ion），是一种金属阳离子，离子符号为Fe3+，是铁原子失去3个电子后形成的离子，是铁的最稳定离子，有较强的氧化性，同时也是一种重要的工业用剂。

2021年10月14日 · Fe3+ displays low solubility at the neutral pH of the intestine and is mainly be converted to ferrous iron (Fe2+) by ferric reductases, as ferric salts are only half as well absorbed as ferrous salts.

2022年9月1日 · The developed sensor exhibited advantages, including simple, low-cost, label-free, rapid, and good sensitivity and selectivity towards Fe 3+ ions, with a great application for detection of such ions in real water.

Achieving low-cost, high-efficiency quantification of Fe3+ ion concentration in unknown solutions can guide environmental management decisions and optimize water treatment processes. In this study, by leveraging the rapid, real-time detection capabilities of nanopores and the specific chemical binding affinity of tannic acid to Fe3+, a linear ...

In chemistry, iron (III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron (III) chloride (FeCl3). The adjective ferrous is used instead for iron (II) salts, containing the cation Fe 2+. The word ferric is …

2023年4月19日 · Visualizing redox-active metal ions, such as Fe 2+ and Fe 3+ ions, are essential for understanding their roles in biological processes and human diseases. Despite the development of imaging probes and techniques, imaging both Fe 2+ and Fe 3+ simultaneously in living cells with high selectivity and sensitivity has not been reported.
