What is Organoclay?

Organoclay, is a sorbent media which is designed to remove organic components. The media is a naturally occurring mineral (commonly zeolite or bentonite clay) which is chemically alternated to create a unique surface on the mineral. The modified surface is designed to create a strong affinity with organic compounds, meaning the media is organophilic. The surface of the media forms a surfactant bilayer which attracts ionic species. Ionic species are components that in solution are grouped as either anionic (anions) or cationic (cations). Anions have a negative charge and cations have a positive charge.
