A Sensitive Determination of Carbofuran by Spectrophotometer using 4, 4‐azo‐bis‐3, 3′5, 5′‐tetra bromoaniline in various Environmental Samples

Abstract

A simple and sensitive spectrophotometric technique was developed for the determination of carbofuran in its formulations, water and grain samples. The method was based on the alkaline hydrolyzed product of carbofuran phenol interacted with diazonium salt of 4,4-azo-bis-3,3′5,5′-tetra bromo aniline. The maximum absorbance of the red coloured derivative was measured at 470 nm. The beer’s law was obeyed in the concentration range of 0.1-16.0 µg/mL. The interference of the non target species were studied on the determination of carbofuran which increases the selectivity of the method. The present method was successfully applied for the determination of carbofuran in its formulations, water and grain samples.

Gas liquid chromatography-flame ionization detector (GLC-FID) residue analysis of carbamate pesticide in freshwater fish Labeo rohita

“…Analytical instrument are used in this study to determine, quantify and confirm pesticide residues in Labeo rohita fish for both research and regulatory purposes. The pesticides are generally analyzed by different types of instruments such as spectrophotometry, 8 thin layer chromatography (TLC), 9 high performance liquid chromatography and gas chromatography, 10 gas chromatography (GC), 11 GC-MS, 12 for carbamate pesticides. 10 The present study describes the method of extraction, clean up and determination of pesticide residues in freshwater fish L. rohita by using gas liquid chromatography (GLC) for the separation.…”
