ANALIYSIS OF RHODAMINE B DYESTUFFS ON LIPTINT USING UV-VIS SPECTROPHOTOMETRY METHOD
نویسندگان
چکیده
Background : Rhodamine B is a synthetic dye that generally used as for paper, textiles or inks. The use of certainly very dangerous health. if directly on the human body will cause irritation respiratory tract and can cancer liver damage. Although there are negative impacts, these dyes still often done, especially food cosmetic products. Purpose This research was conducted to identify determine levels in liptint traded Lubuk Pakam sub-District. Method Qualitative analysis carried out by Thin Layer Chromatography (TLC) using ethylacetate-methanol-ammonia (45:25:30), while quantitative assay UV-VIS Spectrophotometry at wavelength 545 nm. linear calibration curve range 1 - 5 μg /ml resulted regression equation y = 0.0091x 0.009. Results results qualitative showed three samples containing with each Rf value 0.87 cm (sample A), 0.96 B), 0.98 C) quantitatively sample A were known 13,144 mg/g, 27,704 mg/g C 20,386 mg/g. Conclusion From this research, it sub-district
