Lanthanum biosorption by different Saccharomyces cerevisiae strains [PDF]

open access: yes, 2016
Biosorption can be a promising technology in rare earth metal separation and recovery due to the low costs of waste biomasses (used as biosorbents) and the high selectivity exploiting specific interaction between metals and biological active sites.

Further investigation on the degree of deacetylation of chitosan determined by potentiometric titration [PDF]

open access: yesJournal of Excipients and Food Chemicals
The degree of deacetylation (DDA) of various low molecular weight chitosan (LMWC) species as the hydrochloride and free base (amine form) was determined by direct and back potentiometric titration, respectively.

Characterization of a New Zn2+-Selective Electrode Based on Schiff-base as Ionophore

open access: yesInternational Journal of Electrochemical Science, 2012
A new Zn2+-selective electrode based on Schiff-base as ionophore was prepared. Potentiometric responses revealed that this new electrode has good selectivity to Zn2+ relative to a wide variety of other cations.

Potentiometric Titration and Conformational Change in Pepsinogen

open access: yesJournal of Biological Chemistry, 1967
Abstract Potentiometric titrations of pepsinogen as functions of ionic strength and temperature were studied. It was found that the ionic strength has a minor effect on the titration behavior of the protein. The maximum values of the buffering capacity in the pH range of 6.0 to 9.0 were found at pH values corresponding to those at which a ...
