dc.description.abstractA rapid, sensitive and provident flow injection analysis (FIA) method was developed within the framework of a chemometric approach for the quantification of humic acid (HA) in the lignite obtained from Ilgm, Konya, Turkey. The proposed method allows automatic determination of 60 samples per hour over a wide calibration range (0-2000 mg L-1, R-2: 0.9988) and needs only 10 mu L of sample at a flow rate of mobile phase (X-1), 2 mL min(-1); pH of mobile phase (X-2), 8, and system temperature (X-3), 20 degrees C. The limits of detection (LOD) and quantification (LOQ) were calculated as 9.18 mg L-1 and 30.60 mg L-1, respectively, and the relative standard deviation (RSD) for 500 mg L-1 HA was calculated as 3.44 (n: 9). It was revealed that the standard deviation (SD) values of the proposed FIA method are lower than those of the spectrophotometric method. (C) 2014 King Saud University.
