Application of Solid Phase Microextraction and Gas Chromatography for the Determination of BTEX in Solid Petroleum Residues
نویسندگان
چکیده
Este trabalho descreve um método simples e rápido para a determinação de BTEX (benzeno, tolueno, etilbenzeno e xileno) em resíduos sólidos e soluções lixiviadas de resíduos sólidos aplicando a Norma Brasileira ABNT NBR 10004/2004. O método proposto possibilita a detecção direta de BTEX usando microextração em fase sólida e cromatografia a gás com detector por ionização em chama (HS-SPME GC/FID). Os limites de quantificação obtidos para BTEX evidenciaram que o método é adequado para a classificação de resíduos sólidos.

HCl- Etched Steel Fiber for Determination of Phthalates in Water Samples by Solid-Phase Microextraction
In the present work, a stainless steel wire was etched by hydrochloric acid during a chemical etching process. The obtained black layer on the surface of the fiber was used as sorbent for extraction of trace amount of phthalates in the aqueous samples by solid phase microextraction. New fiber efficiency was investigated using a home-made solid-phase microextraction (SPME) device and gas chr...
