Abstract: A novel, efficient, fast, and simple mode of dispersive solid phase extraction based on ferrofluid (FF-DSPE) was investigated for determination of copper in different environmental and food samples. Ionic liquids were used as carrier in this method. Due to rapid injection of ferrofluid into the aqueous sample by a syringe, the sorbent is highly dispersed in the bulk solution, so extraction can be achieved very fast. In addition, the ferrofluid can be attracted by a magnet and no centrifugation step is required for phase separation. The obtained results show that this method can be useful for routine trace laboratory analysis. The influence of different variables on the extraction yield was studied in detail. Under the optimized conditions, the calibration graph was linear over the range of 0.9–90 μg L−1 and the enrichment factor (EF) 267 was obtained. The limit of detection was 0.32 μg L−1 and the relative standard deviation of 2.6 % at 50 ng mL−1 was obtained (n = 6). The method was validated using certified reference material and was successfully applied for determination of copper in various samples.

TL;DR: A method to determine the spectrophotometric biochemical oxygen demand (BOD(sp) was studied with high sensitivity and reproducibility by employing 2,6-dichlorophenolindophenol (DCIP) as a redox color indicator, the yeast Saccharomyces cerevisiae, and a temperature-controlling system providing a three-consecutive-stir unit.

TL;DR: In this article, a binary assay method capable of providing wide dynamic range, a high degree of precision and rapid processing times was proposed, in which analyte is reacted successively with two independently determinable forms of solid-supported binding partner and also with a labelled ligand having affinity for the analyte or binding partner, and analyte concentration was determined from signals deriving from the resulting two forms of analyte-binding partner-labeled ligand systems by reference to a double standard calibration curve.
