Prof. Dr. Ece Tuğba Saka'ya çözünür Cu(II) ftalosiyanin bileşiğinin sentezi için teşekkürker.
DLLME, which is a method that minimizes organic solvent consumption and waste generation, is frequently used for trace analyte determination. In the present work, a simple, selective and sentsitive spectrophotometric method based on the dispersive liquid-liquid microextraction was reported. The procedure is based on the formation of a 1:1 complex between Fe3+ and a water-soluble Cu(II) phthalocyanine and then extraction of this complex into dichloromethane by dispersive effect of acetone. The experimental parameters that effecting the DLLME such as amount of extractive and disperser solvents, pH, salt concentration, Cu(II) phthalocyanine concentration and centrifuging time and rate were optimized. The linear range of the method is 0.4-70.0 ngmL-1 with a good correlation coefficient (R2) of 0.9912. The limits of detection (LOD) and quantification (LOQ) is 0.47 and 1.86 ngmL-1. The relative standart deviation (RSD, %) of the method for 40 ngmL-1 Fe3+ in sample solution (n=11) was 1.4% and the enrichment factor was calculated 240.
