Solid phase extraction separating herbicides from water

It should be pointed out that separation of more than one class of organic compounds can be achieved by SFC. For example. Fig. 1 shows the chromatogram of 35 PAHs, herbicides, and phenols from a contaminated water sample. Solid-phase extraction was used... [Pg.642]

It should be pointed out that separation of more than one class of organic compounds can be achieved by SFC. For example. Fig. 1 shows the chromatogram of 35 PAHs, herbicides, and phenols from a contaminated water sample. Solid-phase extraction was used for sample preparation. Five Hypersil silica columns were coupled in series for separation of these contaminants. The percentage of methanol (as modifier) was varied from 2% (5 min) to 10% (29 min) at 0.5%/min. A pressure program was also applied. A diode-array detector was used in this work. [Pg.784]

The purpose of Experiments 3 and 4 is to present methods for the TLC determination of pesticides. Experiment 3 describes procedures for the separation and detection of organochlorine (OCl), organophosphorus or organophosphate (OP), and Ai-methylcarbamate insecticides and metabolites (Sherma and Bloomer, 1977 Sherma et al., 1977, 1978 Sherma, 1978). Experiment 4 describes the quantitative TLC determination of three classes of herbicides after isolation from water by conventional separatory funnel extraction or solid-phase extraction (SPE) (Sherma, 1986c Sherma and Boymel, 1983). [Pg.457]
