WebSep 13, 2024 · The present invention relates to the use of a tetravinyl silane-polystyrene adsorbent in aniline adsorption, and belongs to the technical field of adsorbent adsorption. The adsorbent is prepared from tetravinyl silane and polystyrene by means of a Friedel-Crafts alkylation reaction, and the amount of aniline adsorbed by the adsorbent is greater … WebAnswer: Pure polystyrene will not expand when heated. You can test this for yourself. The hard clear plastic of CD cases is generally made of polystyrene. Heat it up and it does little but melt or burn. The expandable beads of polystyrene that are used for making Expanded Polystyrene (EPS, or s...

WebThe pores are large enough to allow water molecules to pass through but small enough to restrict the flow of ethanol into the beads. The water saturates the beads, while the dry ethanol passes through the system. High temperatures and a pressure swing vaporize the water within the beads. The beads are re-used for further separation.
WebIf the 10 μm PS beads (ε p = 2.6 and σ p = 0.001 mS m −1) were suspended in DI water (ε m = 79 and σ m = 0.2 mS m −1), the frequency was on the order of 10 kHz for normal particle surface conductivities (about 1 nS). Thus, the 10 μm PS beads in DI water will distribute at the electrode gap under nDEP from 1 kHz to 100 MHz frequencies.
