Enhancement of water stability of MOFs by postsynthesis modification (PSM) Due to the characteristics of MOF materials and PSM methods, the PSM methods are particularly suitable for use with MOFs, which can improve the water stability and expand application range of MOFs, and also can save time and cost (Mandal et al., 2020).The concept of PSM is the introduction of target functional . Mexico's water and sanitation crisis. MIT researchers have produced practical guidelines for generating hydrogen using scrap aluminum and water. Start studying Chemistry test #2. [Aluminum hydroxide hydrogel to remove arsenic from water] Objective: To describe the making of and the preliminary results from an aluminum hydroxide hydrogel that, when added directly to water, can totally eliminate arsenic, regardless of the nature of the water and the oxidation state of the metalloid.
