This study was designed to measure the distribution of pesticides within the mobile phase of simulated irrigation run-off water, using centrifugal split-flow thin-channel (SPLITT) fractionation, a novel technique providing a gentle separation of natural sediment and suspended particles. Particular attention is paid to the extraction of pesticide residues for enzyme-linked immunosorbent assay (ELISA)...
A highly sensitive heterogeneous fluoroimmunoassay has been developed for monitoring phenylurea herbicide diuron on the basis of suppression of fluorescence self-quenching. Specific antibody against diuron was produced and labeled with rhodamine isothiocyanate at different molar ratios and used as tracer in the developed immunoassay. The analytical sensitivity of immunoassay was enhanced by changing...
