The purpose of this study was to fabricate mixed matrix membranes of polyvinyl chloride (PVC) that contain Uio6-NH2 metal–organic framework (MOF) with reasonable wettability for treating mazut/water solutions. The hydrothermal method was used to synthesize Uio66-NH2 particles and then were used with different weight ratios of 0.1, 0.2, 0.3, and 0.4...

In this paper, ultrafiltration polyvinyl chloride (PVC) mixed matrix membranes (MMMs) containing melamine were synthesized via the phase separation procedure in order to remove Sirius Red (SR) dye from the aqueous solution. The amount of melamine loading in the membrane structure was 1, 3, and 5 wt%. The fabricated MMMs were characterized by Fourie...

The goal of the present study is to investigate the effect of adding MgO and Mn2O3 nanoparticles at two different stages of the sol-gel method synthesis procedure of 58S bioactive glass on the bioactivity of the synthesized nanocomposites.
