[ 1 ] - Central Composite Design for the Optimization of Hydrogel Based pH-Dependent Extraction and Spectrophotometric Determination of Mercury

In the present work a pH-dependent cloud point extraction procedure using pH-sensitive hydrogel polymer was applied for preconcentration and spectrophotometric determination of the Hg(II) as its Thio micher's ketone complex. Central composite design (CCD) and response surface method were applied to design the experiments and find out the optimum conditions. Four factors entitled concentration o...
