Web27 nov. 2024 · The as-prepared superhydrophobic/oleophilic cotton fabric was used as a filter membrane during oil/water separation. When the oily wastewater was poured into the separation system, the separation occurred with water remaining in the upper container and oil penetrating the modified cotton fabric and falling into the lower receiving container. WebThe first thing we’ll look at is the separation mechanism of HILIC. This is a separation mode using polar stationary phases. Because the stationary phase is polar, HILIC is well suited for the analysis of polar molecules that have limited or no retention on typical reversed phases. The mobile phases are similar to those used in reversed-phase LC.
