TL;DR: The proposed method was applied to the analysis of four different sources water samples and the relative recoveries of spiked water samples are 99.9-115.7% and 87.3-117.6% at three different concentration levels of 75, 200 and 1000 microg L(-1), respectively.

TL;DR: A new ionic liquid, 1,3-dibutylimidazolium hexafluorophosphate, is described as extraction solvent for extraction and preconcentration of organophosphorus pesticides from water and fruit samples by dispersive liquid-liquid microextraction combined with high-performance liquid chromatography.

TL;DR: An ionic liquid dispersive liquid-liquid microextraction high-performance liquid chromatography method for effective enrichment and determination of nitrite ion in water and biological samples was developed, yielding an excellent enrichment factor and a lower LOD in comparison with other methods.

TL;DR: In this paper, a simple, rapid and efficient method, dispersive liquid-liquid microextraction (DLLME) in conjunction with high-performance liquid chromatography (HPLC), has been developed for the determination of three carbamate pesticides (methomyl, carbofuran and carbaryl) in water samples.

TL;DR: In this article , the effects of concrete cover, stirrups spacing, and steel bar corrosion level were experimentally studied using beam-type specimens, and the results suggested that the bond strength of LWAC specimen was improved by the increase in concrete cover and the decrease in the spacing of stirruppers.
