“…The ultraviolet-visible (UV-vis) spectrum of the DPC ligand has a unique prole because of the obvious broad band in the visible region at about 550 nm. 28 Moreover, because of the presence of four acidic protons, DPC is a pH-sensitive ligand, and when the pH increases to 12, the molar absorptivity gradually increases ( Fig. 1(b) inset).…”

“…Los picos de oxidación 0i y 01 corresponden a la oxidación de la DPCI a DPCOO (76]; y los picos de reducción R2 y RJ son asociados al proceso de reducción de la DPCOO a DPCI (76].…”

“…A los 0.85 mi aparece un pico en 320 nm y una banda ancha de absorción entre 500 y 600 nm, con un máximo a 540 nm. El máximo de 320 nm corresponde al pico característico de la DPCOO [71,76] y el de 540 nm al pico del complejo formado DPCO-Cr (III), en la reacción de DPCI con Cr (VI) [14][15][16][17][18]. A partir de los 0.9 ml en adelante los espectros muestran el máximo de 540 nm y el máximo que se observaba a los 252 nm se va moviendo hasta llegar a 233 nm, el pico de 320 nm se observa como un hombro; este comportamiento se observa hasta la adición de 1.30 mi de titulante.…”
