Application of Potentiometric and Electrophoretic Measurements to Evaluate the Reversibility of Adsorption of Divalent Ions from a Solution on Titanium Dioxide

Molecules
The adsorption of divalent ions on metal oxides is controlled by the pH of a solution. It is commonly assumed that this is a reversible process for pH changes. However, there are reports that the sorption of ions on oxides may not be reversible.

Surface stoichiometry of zinc sulfide and its effect on the adsorption behaviors of xanthate

Chemistry Central Journal, 2011
In this paper, the surface stoichiometry, acid-base properties as well as the adsorption of xanthate at ZnS surfaces were studied by means of potentiometric titration, adsorption and solution speciation modeling.

Water Drops Sliding Over Arrays of Janus Micropillars With Hydrophilic Tops: A New Mechanism of Drop Charging

Small, EarlyView.
A water drop slides over a distance of a few centimeters across arrays whose top surfaces exhibit a contact angle below 10°. The arrays are fabricated with hydrophilic tops and hydrophobic sidewalls and substrate, forming Janus structures. As the drop moves, it generates a spontaneous electric charge and leaves behind tiny satellite droplets that ...

Characterisation of reduction state of cystine linkages on wool fibre surface under heterogeneous reaction conditions

Polymer Testing, 2022
As a natural biomaterial with outstanding properties, keratin fibres hold promising potential in many application fields. The reduction of disulphides in keratin to the corresponding thiols plays a central role e.g.

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

THIOCYANATE ION-SELECTIVE PVC MEMBRANE ELECTRODE [PDF]

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2010
A potentiometric selective sensor based on trinuclear chromium(III) complex as a novel ionophore for the thiocyanateselective electrode is reported. The sensor displays a near Nernstian slope of 57 ± 2 mV per decade, over a wide pH range 3 - 11.

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1677-1691, April 2026.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Modelling and optimization of surfactant sensor response characteristics for the use in surface water and wastewater analysis

Zaštita Materijala, 2014
The theoretical model of potentiometric titration curves of sodium dodecyl sulfate (anionic surfactant) was proposed and the response parameters of two surfactant sensors (commercial and self-made) were investigated.

Single Solid‐State Ion Channels as Potentiometric Nanosensors

Advanced Functional Materials, Volume 36, Issue 18, 2 March 2026.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

A computer‐controlled potentiometric/spectrophotometric titrator [PDF]

Journal of Analytical Methods in Chemistry, 1988
A laboratory computer controlled potentiometric titrator interfaced to a diode array spectrophotometer is described. The titrator consists of widely used, commercially available components; therefore, major attention is given to modes of interconnection and software implementation in data format and system control.
