Abstract
The invention discloses a floating absorbent and a preparation method and application thereof. The floating absorbent comprises hollow glass beads and a silane coupling agent, wherein the silane coupling agent is grafted onto the outer surface of each hollow glass bead; the silane coupling agent is a silane coupling agent with specificity on dye; the mass ratio of the hollow glass beads to the silane coupling agent is (1 to 2):1. The preparation method comprises the following steps of firstly, pretreating the hollow glass beads; enabling the pretreated hollow glass beads to react with the silane coupling agent; finally, drying, so as to obtain the floating absorbent. The floating absorbent has the advantages that the dissolvable pollutants can be effectively treated; the floating absorbentenriching the pollutants can stably float up, so as to quickly separate the pollutants and a water body.
