Problem: Organic pollutants in the aquatic environment disrupt ecosystems, have an impact on the health of organisms and, as a result, cause economic losses.
Solution: A magnetic sorbent based on Fe3O4 microparticles was developed, subsequently modified by silanization and a C18 functional group. This sorbent has the ability to efficiently remove non-polar substances from water. The prepared sorbents were tested for BTEX and PAH removal efficiency. Up to 99% of xylenes, 95% of ethylbenzene, and more than 90% of polyaromatic hydrocarbons can be removed.
