Spectrometric Determination of Manganese in Spring Waters after Rapidly Synergistic Cloud Point Extraction

Abstract

In this study, the rapidly synergistic cloud point extraction (RS-CPE) method, which is an improved version of cloud point extraction (CPE), has been used. Based on this method, spectrometric determination (the flame atomic absorption spectrometry (FAAS)) of the manganese (Mn) was carried out in Sivas hot spring water (HSW) and in cold spring water (CSW) after extraction in the presence of synergistic reagent and a complexing agent. The effect of pH, amount of surfactant, amount of complexing agent, amount of synergistic cloud point regulator and solvent species used to reduce the viscosity of the organic phase on extraction were investigated. Optimum conditions were found to be 7.00; 6.90 for pH, 0.15%; 0.18% (v/v) for surfactant, 7.07×10-5; 8.08×10-5mol L-1 for complexing agent, 0.8; 0.6 mL for synergistic cloud point regulator HSW and CSW, respectively. It was also found to be methanol solution for solvent type (1.0 mol L-1 with nitric acid), HSW and CSW, respectively. Matrix-compatible calibration was determined at a range of 2-120; 3-120 μg L-1 with a detection limit of 0.56; 0.87 μg L1, HSW and CSW, respectively. A sensitization improvement of 109.1; 105.5 after enrichment resulted in a preconcentration factor of 40 for the 40.0 mL sample HSW and CSW, respectively. After the addition of 50.0 μg L-1 manganese to the matrix, the precision was 3.15% and 3.8% and recovery of the five replicate measurements and 97.2%; 96.5%, HSW and CSW, respectively. The soluble Mn concentration was 85.2; 32.7 μg L-1 from the sample analysis performed under optimum conditions, HSW and CSW, respectively
