Gongye shui chuli, 2018 文章研究了柠檬酸螯合Fe（Ⅲ）活化过硫酸盐体系对水中活性艳红X-3B的降解效果。考察了过硫酸盐浓度、Fe（Ⅲ）/柠檬酸（CA）、pH及阴离子（NO3-、NO2-、HCO3-、Cl-）对X-3B降解效果的影响，并研究体系中产生自由基的贡献率。结果表明，过硫酸盐浓度为0.2 mmol/L时，X-3B降解率最大；X-3B的降解率随Fe（Ⅲ）/CA增大而增大；pH的增大不利于X-3B的降解；无机阴离子的加入抑制X-3B的降解。·OH和SO4 ·－在光解过程中的贡献率分别为58%和31%。

Gongye shui chuli, 2013 以活性艳红X-3B为模拟底物,研究了低温常压条件下CuO-H2O2体系催化氧化染料废水的各种影响因素及反应机制。结果表明,CuO-H2O2体系能高效彻底地氧化活性艳红X-3B,氧化率可高达99%。CuO-H2O2体系降解染料废水的速率随温度、氧化剂和催化剂投加量以及X-3B废水初始浓度的升高而升高。酸性条件能促进X-3B废水的降解。与直接染料相比,CuO-H2O2体系降解活性染料废水更加有效。

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.
