Spe Method

Asolid-phase extraction (SPE) method, coupled with HPLC/DAD and GC/FID analysis has been developed for the simultaneous determination of simazine, atrazine and propazine in water samples. The compounds of interest were enriched on Envi-carb SPE tubes. The recoveries for simazine, atrazine and propazine from spiked Nanopure water were 101 5.6 %, 99 4.9 % and 96 5.7 %, respectively. The detection limits were 4.00, 8.00 and 10.00 ng absolute samplemass in the column for simazine, atrazine and propazine, respectively. Standard curve r2 values of 0.9828-0.9988 for the analyzed compounds were consistently obtained.
