Application of solidification of floating organic drop microextraction for inorganic anions: Determination of phosphate in water samples

Application of Solvent Demulsification-Dispersive Liquid-Liquid Microextraction Based on Solidification of Floating Organic Drop Coupled with High Perfomence Liquid Chromatography in Determination of Sulfonylurea Herbicides in Water and Soil

“…It is capable of being used in the analysis of environment samples such as surface water, conduit water and loam soil. The detection limits of the proposed method was 0.24-0.81 μg L -1 and 2.42-8.12 μg kg -1 , which can be in accordance with the other methods described in the literature, 10,[21][22][23][24] so do the recoveries and RSDs.…”

“…This method improves the mode of phase separation of SFO-DLLME to make it possible to be used in field processing and automated analysis without electric centrifugal equipment. 21 It has been successfully applied in the determination of organic and inorganic compounds such as phosphate, 22 heavy metals, 23 amphetamines, 24 organochlorine pesticides, 25 polycyclic aromatic hydrocarbons. 26 In this paper, the method of SD-SFO-DLLME (solventbased demulsification and solidification of a floating organic drop combined with dispersive liquid-liquid microextraction) with HPLC-UV analysis was developed for the determination of sulfonylurea herbicide residues in water and soil samples.…”

Europium-based infinite coordination polymer nanospheres as an effective fluorescence probe for phosphate sensing

“…To achieve the objective mentioned above, various analytical strategies have been devoted for the effective identication and determination of Pi, including colorimetry, chromatography, electrochemical method, enzymatic biosensors and so forth. [5][6][7][8][9] Nevertheless, there exist several inherent drawbacks for these proposed methods, which usually require expensive instruments, tedious sample pretreatment together with professional operators, making them impractical for regular environments analysis. By comparison, the uorescence-based sensing has drawn extensive attention because of its high sensitivity, selectivity, fast response time, simple operation, and accessible instrument requirement.…”

Vortex‐assisted natural deep eutectic solvent microextraction using response surface methodology optimization for determination of orthophosphate in water samples by molybdenum blue method

“…The preconcentration factor, calculated as the ratio between the sample volume and the settled down NADES volume, was obtained as 71. A comparison of the analytical performances achieved by the proposed method and other methods for determination of orthophosphate is presented in Supporting Information . Compared with previous reports, the proposed method has many advantages, such as simplicity, short analysis time as well as the use of NADES as an eco‐friendly solvent with high solubilization power for both polar and nonpolar compounds and low cost.…”
