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

化学计量学在超声辅助分散液-液微萃取同时测定染料的建模和优化中的应用

随着世界人口的持续增长,水资源的污染也在增加。因此,重要的是找出减少污染的方法,这是我们努力显着增加清洁和安全水供应量的一部分。在这项研究中,研究了超声辅助分散液-液微萃取(UA-DLLME)作为一种快速,经济,简单的方法从水样中提取孔雀石绿(MG)和若丹明B(RB)染料的效率。在最佳条件下,RB和MG的线性动态范围(LDR)分别为7.5–1500 ng mL -1和12–1000 ng mL -1。检测限(LOD)为1.45 ng mL -1和2.73 ng mL -1,定量限(LOQ)为4.83 ng mL -1RB和MG分别为9.10 ng mL -1。提取效率在95.53–99.60%的范围内。实际水和废水样品中的相对标准偏差(RSD)小于3.5。该方法成功用于水样中RB和MG染料的测定,结果令人满意。
