Chemical association of copper and selenium in coals of Sindh by time saving single step strategy and their impact on groundwater

Deep eutectic solvent-based dispersive liquid–liquid microextraction followed by smartphone digital image colorimetry for the determination of carbofuran in water samples

“…In DLLME, a mixture of extraction solvents and dispersive solvents were injected into aqueous samples for rapid extraction. 11,12 In addition to dispersive solvents, the extraction solvents appeared as ne droplets dispersed in the water sample. This enhanced the mass transfer of analytes from the sample matrix to the extractant phase.…”
