Abstract
In this thesis we developed a method based on dispersive liquid–liquid microextraction (DLLME) coupled to UV-Vis spectrophotometry for determination of Rose Bengal (RB) in water samples. The extracted Rose Bengal was separated and quantified by UV–Vis spectrophotometry.The influence factors relevant to DLLME, such as type and volume of extractant and disperser solvents, pH, salt effect and extraction time were optimized. Under the optimal condition volum of the aceton as disperser solvent 2.00ml, volum of octanol as extraction solvent 300 μl, extraction time 5 min and concentration of NaCl 10% (w/v) and pH=2 were obtained. Also limit of detection for Rose Bengal was 0.05 μg/ml. the proposed method was applied to the determination of Rose Bengal in water samples with satisfactory analytical results. The proposed method was simple, rapid and sensitive for the detection of Rose Bengal.
