DEVELOPMENT OF THE METHOD FOR DETERMINING THE CONTENT OF THE SYNTHETIC DYE DIAMOND BLUE FCF IN THE SORPTION MATERIAL BY THE HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY METHOD

Introduction. To date, the use of unmanned aerial vehicles (UAVs) in Ukraine for agricultural lands treatment is a new promising technology that requires detailed study and development approaches to risk assessment hygienic regulation. Development method will allow measuring content diamond blue FCF sorption material (filter paper) relevant. The aim – determining synthetic dye by high-performance liquid chromatography method. Research Methods. following materials were used: laboratory analytical balance Radwag® AS220.R2, rotary evaporator, cartridge Strata™ C18-e (55 μm, 70 °С) 500 mg/6 ml, f. Phenomenex, steel chromatographic column 150/4.6 Microsorb 100-5 C18, pre-column 4/3 chromatograph “Shimadzu” with diode array detector, Diamond FCF, standard, 87.7, paper filters de-ashed “red ribbon”. Results Discussion. At first stage research, samples taken prepared. For analysis, 2 parallel taken. next was preparation sample introduction into chromatograph. third performing. final stage, peak areas determined calculated on chromatograms. indicated includes extraction from distilled water; solid-phase quantification reversed-phase HPLC SF detection. This differs known ones it makes possible determine investigated material. Conclusion. proposed containing evaluate effectiveness safety various models UAVs combination pesticide preparations when using different agrotechnical characteristics at pre-registration trials scientific research.
