Triangle potentiometric titration

In this automatic system, the authors preferably used coulometric generation of titrant (cf., microcoulometric determination of deviations in the above end-point titration ), e.g., H, OH, Ag, Hg2+, Br2,12, Fe(CN) (cf., Table 1 in ref. 63). The detection method may be potentiometric (logarithmic signal), amperometric (linear signal), biamperometric, conductometric, oscillometric, etc. Moreover, the authors evaluated triangle programmed titration curves by...

Open circles, non-imprinted resin solid circles, Cu(Il)-imprinted resin solid triangles, Zn(II)-imprinted resin solid squares, Cd(II)-imprinted resin. Conditions 0.5 g of resin and Ckno.i = 0.1 mM, at 25°C for a potentiometric titration.

Fig. 5 Potentiometric titration curves for branched PAAs with comonomer ratios y=100 (circles), 10 (triangles), 2.5 (squares) in aqueous solutions. The filled squares indicate the region where the branched PAA at y=2.5 was insoluble in aqueous solution. (Reproduced with permission from Ref. [127]. Copyright 2002 American Chemical Society.)...
