Samplers air pollutants.

摘要

Samplers air pollutants. The present invention relates to a process for the synthesis of a compound consisting of the formula (SiO {sub, 2}) (Cyclodextrin) {sub, x}, (where x represents the molar fraction and real-valued defined within the range from 0 to 0.002), the compound itself characterized by said formula, the use thereof as a solid phase or fill samplers for the uptake of atmospheric organic contaminants (VOCs), and samplers themselves comprising as solid phase or filling said compound characterized by formula (SiO {sub, 2}) (Cyclodextrin) {sub, x}.
