Síntesis y caracterización de partículas de SiO2 y TiO2 modificadas con poliestireno para extracción por dispersión de matriz en fase sólida
Palabras clave:
Sol-gel, partículas híbridas, poliestireno, plaguicidas, extracción en fase sólida
Resumen
Se sintetizaron partículas de SiO2 y TiO2 por sol-gel, utilizando como precursores el tetraetil ortosilicato e isopropóxido de titanio, respectivamente. Las partículas se funcionalizaron con grupos vinilo, sobre los cuales se polimerizó el estireno; las partículas se caracterizaron por microscopía electrónica de barrido con análisis por espectroscopía de energía dispersiva, espectroscopía infrarroja con transformada de Fourier y análisis termogravimétrico. Estas partículas se emplearon para la extracción de tres plaguicidas organofosforados de puré de tomate por dispersión de matriz en fase sólida (MSPD). Los plaguicidas se eluyeron con acetato de etilo y los extractos resultantes se analizaron por cromatografía de gases con detección por espectrometría de masas. Se observó que el área de los tres plaguicidas en el extracto obtenido utilizando partículas de SiO2-poliestireno fue mayor que las áreas en los extractos obtenidos usando TiO2-poliestireno o en ausencia de partículas. Estos resultados sugieren la viabilidad de utilizar partículas de SiO2-poliestireno como sorbentes para la extracción de plaguicidas de frutas y hortalizas por MSPD.
