Abstract

A comparison of derivatization step influence on the method extraction of mercury species has been carried out. Experimental design generated by using central composite design was used to optimize the extraction parameters. Signal response of targeted analytes, which accounts as sum of peak areas has shown maximum response (y=276920, in-matrix derivatization) slightly higher compared to on-fiber derivatization (y=274883). In both cases, two variables namely the concentration of solution and exposure time contribute significantly (ANOVA, p
