Abstract
We describe a rapid, sensitive, fluorescent screening test for xylenes in water samples that avoids more costly time-consuming methods. The screening test is based on a molecularly imprinted polymer and it runs without the need for any pre-concentration step, thus rendering it suitable for routine use in water-quality-control laboratories. The test recognizes contaminated samples rapidly (50 s) and inexpensively with a cut-off level of 10 μg mLâ 1, which is the value that the International Organization has laid down in its assessment of the water quality for human consumption. The reliability of the screening test was 23% false positives and 0% false negatives in 30 samples. The applicability was confirmed by analyzing mineral, tap and river water samples.
