Experiments on Water Stabilization

The aim of the study was assessment of groundwater stabilization. Corrosive water effects on metals include complex electrochemical and biochemical processes. None of the water components remain indifferent to the metal and can accelerate or delay its corrosion. On the basis of the conducted tests of water samples, the aggressiveness and corrosivity indicators were calculated. Conducted research included analyses of raw and treated water. Raw water was taken as groundwater. Then it was treated in individual and complex processes such as aeration, filtration and ion exchange. Water aggressiveness and corrosion level were introduced by the Langelier Saturation Index (LSI), the Ryznar Stability Index (RI), the Larsoni–Skold Index (LI) and the Singley Index (SI). Obtained results proved that used water treatment processes must be improved through additional aeration and filtration with a dolomite bed. A simple system typical for industrial water is not enough to reach stable water because of remaining aggressiveness and corrosion.

Water stabilization of Zr6-based metal–organic frameworks via solvent-assisted ligand incorporation

Water stability in metal–organic frameworks (MOFs) is critical for several practical applications; we report here fundamental understanding how capillary forces induce damage to MOFs and highlight that metal node functionalization as a strategy to create vapor-stable and recyclable MOFs.
