|Title:||New Sorbents Based On Poly(methyloctylsiloxane) Immobilized On Silica For Use In Solid-phase Extraction [novos Sorventes Baseados Em Poli(metiloctilsiloxano) Sobre Sílica Para Uso Em Extração Em Fase Sólida]|
|Abstract:||This paper presents an easy and practical procedure to obtain silica-based C-8 type sorbents for use in solid-phase extraction. The materials are prepared by depositing poly(methyloctylsiloxane), PMOS, on the silica support. Two different treatments for immobilization were used: thermal treatment or gamma irradiation. Suitable recoveries were obtained after pre-concentration of dilute solutions, at the ng/L level, of a mixture of pesticides, indicating the good performance of the materials.|
