Application of chemometrics for modeling and optimization of ultrasound-assisted dispersive liquid–liquid microextraction for the simultaneous determination of dyes

Abstract As the world population continues to grow, so does pollution of water resources. It is, therefore, important identify ways reducing as part our effort significantly increase supply clean and safer water. In this study, efficiency ultrasound-assisted dispersive liquid–liquid microextraction (UA-DLLME) a fast, economical, simple method for extraction malachite green (MG) rhodamine B (RB) dyes from samples is investigated. optimal conditions, linear dynamic range (LDR) RB MG 7.5–1500 ng mL ?1 12–1000 , respectively. The limit detection (LOD) 1.45 2.73 quantification (LOQ) 4.83 9.10 MG, Extraction obtained in 95.53–99.60%. relative standard deviations (RSD) real wastewater are less than 3.5. developed used successfully determination there satisfactory results.
