ecletica-626	Gaubeur, Ivanise; Rossi, Maura Vincenza; Iha, Koshun; Suárez-Iha, Maria Encarnación Vázquez	Amphoteric behavior of di-2-pyridyl ketone benzoylhydrazone in ethanol-water mixtures*	2000	13	.pdf	application/pdf	4327	318	58	Before each measurement of the pH (-log aH) for the DPKBH solutions, in different ethanol percentage, the glass electrode was calibrated at (25.0 ± 0.1)° C with 0.0500mol. The properties of DPKBH solutions must be known at different ethanol-water percentages in order to achieve higher sensitivity and/or selectivity for metal analysis.	cache/ecletica-626.pdf	txt/ecletica-626.txt
