Abstract
A superpolar sorbent network is a sol-gel network of at least one metal oxide precursor condensed and at least one polyhydroxy molecule. The metal oxide precursor is a silicate precursor, aluminate precursor, titanate precursor, zirconate precursor, germinate precursor, or any combinations thereof, and the polyhydroxy molecule has a multiplicity of hydroxyl groups. The polyhydroxy molecule can be an organic molecule derived from nature. The superpolar sorbent network can be used as a particulate or bulk sorbent for sampling or removal of analytes or contaminants from an environment or can be coated on a tube or particulate substrate for use as a chromatographic stationary phase.
