“…The advantages of SPE include faster analysis, reduced solvent usage, and possibility to connect online with analytical techniques such as liquid chromatographymass spectrometry (LC-MS) (Smith and Lloyd 1998;Hennion 1999). LC-MS has been utilized successfully in the analysis of organic micropollutants (Slobodník et al 1997) and phenols (Wissiack et al 2000). The direct sample introduction to the LC system leads to better sensitivity and lower detection limits.…”

Compared to the conventional methods used for this purpose, the main benefits of the method are rapidity of measurement, simplicity of use, and absence of the need for multistage sample treatments (short analysis time). For this reason, this online method is more suitable for the control of papermaking by analyzing the concentration levels of interfering substances (i.e., selected resin and fatty acids) than an offline analysis detailing all the individual extractives-based compounds in process streams. It is also obvious that the technique can easily be modified for other environmental pollutants as well.

“…The EEC Directive 80/778, concerning the quality of water designated for human consumption, establishes the maximum admissible concentration of each individual pesticide at 0.1 lg/L and the total amount of pesticides at 0.5 lg/L [2]. As regards surface water, the detection of many organic compounds is typically required at levels of 1 -3 lg/L [3,4].…”

Development and validation of a high-performance liquid chromatographic procedure for the determination of herbicide residues in surface and agriculture waters A procedure has been developed for the determination of quinclorac, bentazone, 2,4-D, clomazone, and propanil residues in surface and agriculture waters by SPE and HPLC-UV. The method was validated and was applied for levels between 0.1 and 0.5 g/L, after a 500-fold pre-concentration. Average recoveries ranged from 85.7 to 109.8% with overall relative standard deviations of 1.8 to 13.4%.

SummaryEvaluation of a simple and rapid method for determination of cJomazone in environmental water samples, by high-performance liquid chromatography with ultraviolet detection, is described. After solid-phase extraction with Cl8 extraction cartridges clomazone was separated on a Cl8 column with 65:35 (v/v) methanol-water, pH 4.0, as mobile phase at a flow-rate of 1.0 mL min 1. After optimization of the extraction and separation conditions, the method was used for determination of clomazone residues in rivers and agricultural waters of the central region of the Rio Grande do Sul province. The results revealed that clomazone persists in agricultural water at least for 130 days, and was present in 90% of the river water samples analyzed.
