ABSTRACT
Trace organic compounds in water
are often environmentally significant but difficult to detect.
Therefore, water samples are typically concentrated before
analysis. However, conventional sample preparation methods
can account for two thirds of the total length of time of the
analytical procedure and are often the rate-limiting step for
the analysis of organic compounds in water. This presentation
introduces an inexpensive method that is capable of screening
water for the presence of target compounds so that time-consuming,
quantitative analyses are reserved for samples where the presence
of the target compounds has been confirmed. The method was
tested in both laboratory and field applications and a variety
of organic compounds (estrone, estradiol, estriol, 17-a ethynylestradiol,
ibuprofen, diazinon, chlorpyrifos, butylated hydroxyanisole
(BHA), butylated hydroxytoluene (BHT), and caffeine) were evaluated
for their compatibility with the method.
