Points of Zero Charge and Potentiometric Titrations

open access: goldAdsorption Science & Technology, 2003
Based on the various categories of surface charge and the definitions of points of zero charge proposed by Sposito (1984, 1998), the determination of the adsorbed proton charge (σ H ) and the point of zero net charge (PZNPC) of insoluble oxides and layer

No-Aqueous Titrations: Potentiometric Titration of Some Primary Amines

open access: yesReviews in Analytical Chemistry, 2008
Potentiometric titrations of some primary amines; I-aminobutane, Iaminopropane and 3-amino-l-phenylbutane were carried out with hydrochloric acid in toluene solvent. The same titrations were done with hydrochloric acid in methanol solvent to show the effect of amphiprotic solvent in the titrations with hydrochloric acid.

Investigation of the functional groups on the surface of activated carbons [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Activated carbons were produced in the laboratory from wood using a 20-run Plackett–Burman experimental design for 19 factors. The obtained batches of activated carbon were analysed by potentiometric titration and FTIR spectroscopy to determine the ...
