De antemano gracias

The most selective and sensitive phases used in SPE
are based on immunoaffinity or molecular imprinted
polymers (MIPs). The high production cost of
immunoaffinity columns explains the lack of recent
applications to soil analysis. As an option, MIPs are
more economic and highly stable polymers; they have
recognition sites within the polymer matrix that are
adapted to the 3-D shape and functionalities of an
analyte. Turiel et al. [10] presented an interesting
application of MI-SPE to group-selective extraction of
triazine and TPs in soils. They extracted five chlorotrizines
(propazine, atrazine, simazine, desethylatrazine
and desisopropyl atrazine) and one methylthiotriazine
(prometryn) on a propazine imprinted polymer. They
loaded 1 ml toluene extracts from soil on the MI-SPE
column and eluted the analytes with 8 ml of acetonitrile.
Recoveries were higher than 94% for the chlorotriazines
and 39% for prometryn. Fig. 2 is an
electropherogram depicting the extraction of triazines
and the clean-up efficiency. It should be taken into
account that MIPs are always less usable for enrichment
of many different compounds or of unknowns.

extracción selectiva de grupos (químicos)
Explanation:
La muestra a ser analizada se procesan con técnicas de separación selectivos.
Uno de los métodos es dispersar la muestra en solventes de polaridad creciente, hexano, acetonitrilo, alcoholes, agua, etc. Hay oytros métodos que implican otras propiedades físicas
