章節(jié)摘錄
Purification. The filtrate resulting from sample extraction is a complex mixturethat contains organic solvent(s), water, biochemicals (lipids, sugars, amino acids, andproteins), and secondary metabolites (organic acids, alkaloids, terpenoids, etc.) at highconcentrations with very minute amounts of the pesticide residues of interest. It is achallenging task to isolate and detect pesticide residues of interest in the presence ofhigh levels of background chemicals, often called matrix interferences. Most crudeextracts require some purification prior to analysis. Purification involves the removal of water, evaporation of excess organic solvent,and selective trapping to separate pesticides from interferences. The greater the numberof cleanup steps included in a method, the greater the losses of analytes and the longerit takes to carry out the analysis. Most of the water must be removed from the extract tofurther concentrate the desired analytes. Much water is quickly removed by partitioningthe organic solvent with sodium chloride-saturated water. These techniques removelarge amounts ofthe water, but the remaining traces of water must be removed byfiltering or adding dehydrated hygroscopic salts (e.g., Na2SO4) to the organic phase ofthe extract. Recoveries of extremely water-soluble pesticides such as acephate andmethamidophos can vary depending on the concentration of other solutes and themechanism of water removal. Even after the removal of many water-soluble coextractives, extracts still containlarge amounts of interfering compounds and only trace levels of pesticide residues.Buffering the aqueous phase close to a pH of 7 prior to removing water causes moreionic and polar biochemicals to partition into the water and results in removing largequantities of organic acids from the organic phase, which contains neutral and nonpolarchemicals, including pesticide residues. It is also possible to remove large amounts ofnonpolar plant constituents before removing the water by filtering the aqueous/organicextract through reversed-phase solid-phase extraction (SPE) material or an activatedcarbon sorbent. Because extracts must be concentrated lO0-fold or more, a requirement for traceresidue analyses, rapid and efficient concentration techniques are preferred. Rotaryevaporators and Kudema-Danish sample concentrators are good for concentratingthermally labile and highly volatile pesticides. Heating the extract in an open beakerwith a stream of gas is also an efficient and inexpensive way to achieve concentration.
