Chlorine (Cl) and hydrogen chloride (HCl) are heavily utilized industrial chemicals that present significant respiratory health risks. The metal-organic framework UiO-66-NH has shown an unprecedented ability in powder form to remove chlorine gas. Here, we engineered UiO-66-NH into 20×40 mesh granules and evaluated their ability to remove chlorine and hydrogen chloride gas challenges. The exposed materials were characterized with nitrogen isotherms, powder X-ray diffraction, and attenuated total reflectance - Fourier transform infrared spectroscopy. Breakthrough results revealed that UiO-66-NH sorption of chlorine and hydrogen chloride met or exceeded sorption of state-of-the-art metal-impregnated activated carbon materials on a mass and volume basis in engineered form.
氯（Cl）和氯化氢（HCl）是两种广泛应用的工业化学品，它们对呼吸系统健康具有显著危害。金属有机骨架 UiO-66-NH 在粉末形式下表现出了前所未有的去除氯气的能力。在此，我们将 UiO-66-NH 加工成 20×40 目颗粒，并评估了其去除氯气和氯化氢气体挑战的能力。通过氮气等温线、粉末 X 射线衍射和衰减全反射-傅里叶变换红外光谱对暴露的材料进行了表征。突破结果表明，UiO-66-NH 对氯气和氯化氢的吸附在工程化形式下，无论是基于质量还是体积，都超过了最先进的金属浸渍活性炭材料的吸附。
