Abstract Solid‐state electrolytes (SSEs) are promising for lithium batteries with higher safety, cycling stability, and energy density. Among the various SSEs, solid polymer (SPEs) a highly preferred choice due to their high thermal thin design, good formability. However, have low ionic conductivity, example, polyethylene oxide (PEO), one of most dominant polyelectrolyte materials, has conductivity at room temperature its crystallinity. Theoretically, increasing active sites by decreasing...
Determination of 23 organophosphorous pesticides (sulfotep, phorate, demeton, diazinon, disulfoton, kitazzin.P, chlorpyrifosmethyl, methyl-parathion, ronnel, fenitrothion, malathion, chlorpyrifos, fenthion, parathion, bromophos, isofenphos-methyl, phenthoate, quinalphos, ethion, triazophos, carbophenothion, pirimiphos-methyl, and pirimiphos-ethyl) in water using solid-phase microextraction (SPME) with gas chromatography-mass spectrometry detection (GC-MS) was investigated. The influence...
A new simple and rapid pretreatment method for simultaneous determination of 19 sulfonamides in pork samples was developed through combining the QuEChERS with dispersive liquid-liquid microextraction followed by ultra-high performance liquid chromatography tandem mass spectrometry. The sample preparation involves extraction/partitioning using tetrachloroethane as extractive solvent acetonitrile extract that obtained QuEChERS. enriched organic phase evaporated, reconstituted 100 μL...
A convenient and versatile method was developed for the separation detection of alkaline earth metal ions by ion chromatography with indirect UV detection. The chromatographic Mg 2+ , Ca Sr performed on a carboxylic acid base cation exchange column using imidazolium ionic liquid/acid as mobile phase, in which liquid acted an UV‐absorption reagent. effects liquids, wavelength, acids temperature retention were investigated. main factors influencing background absorption reagent concentration...
Using imidazolium ionic liquids as ultraviolet absorption reagents and eluting agents for the indirect UV detection of pyrrolidinium cations.
Abstract An analytical method was developed for the simultaneous determination of thiocyanate and iodide by reversed‐phase liquid chromatography with UV detection using imidazolium ionic liquids as mobile phase additives. The chromatographic behaviors two anions on a C 18 column were studied compared four types reagents including liquids, pyridinium 4‐aminophenol hydrochloride tetrabutylammonium effects concentrations organic solvents wavelength separation investigated. role retention rules...
Abstract Fouling of heat exchanger surfaces during sugar manufacture reduces productivity and increases energy demand. This study characterizes a deposit (including its internal structure) formed in factory's evaporator unit using variety X‐ray diffraction scanning electron microscopy techniques powder diffraction, fluorescence, elemental mapping with dispersive spectroscopy backscattered imaging). Calcium sulfate dihydrate, calcium oxalate mono‐ hydroxyapatite, amorphous silica organic...
Indirect ultraviolet detection was conducted in ultraviolet‐absorption‐agent‐added mobile phase to complete the of absence absorption functional group analytes. Compared with precolumn derivatization or postcolumn derivatization, this method can be widely used, has advantages simple operation and good linear relationship. Chromatographic separation Li + , Na K NH 4 performed on a carboxylic acid base cation exchange column using imidazolium ionic liquid/acid/organic solvent as phase, which...
The composite fouling of calcium oxalate monohydrate (COM) and amorphous silica (SiO2) were investigated in a dynamic system under subcooled flow-boiling novel but simple continuous evaporation setup to simulate the operation cycle latter effects sugar mill evaporators. Simulated solutions with various COM SiO2 supersaturation (SS) ratios as well those pure tested for comparative studies. results demonstrated that resistances began rise shortly after experiment started highest extent...
