The Development of pH Modulated Solidified Homogeneous Liquid Phase Microextraction Methodology for Preconcentration and Determination of Nickel in Water Samples

Abstract

Abstract: In this work, a new, fast and green pH assisted solidified homogeneous liquid phase microextraction method (pH-MS-HLPME) was developed. Initially, the complex formation of Ni-1-Phenylthiosemicarbazide (Ni-PTC) and the dissolution of the extraction solvent (caprylic acid) in water were achieved by addition of NaOH. After base addition caprylic acid (CA) become completely soluble as sodium caprylate in model solution. The phase separation of extraction solvent was accessed by addition of HCl. The analyse of nickel concentrations was carried out by micro-sampler adapted flame atomic absorption spectrometer. Under optimized parameters, linear range (10.0-450 μg L-1), detection limit (3.2 μg L-1), limit of quantification (10.0 μg L-1), relative standard deviation (2.0 %), relative error (-3.9 %), and preconcentration factor (45) were calculated, respectively. Finally, the developed pH-MS -HLPME methodology was successfully applied to LGC 6010 hard drinking water (CRM) and some water samples.
