Solubility Part 1: Overview

Critical size effect for the surface heat capacities of nano-CdS: theoretical and experimental studies

“…In this study, nano-CdS were prepared using the solvothermal method. The solubility technology 53,54 was used in combination with the theory of dissolution thermodynamics, the principle of thermodynamic cycle method and the principle of electrochemical equilibrium to determine the conductivity of nano-CdS in an aqueous solution and obtain the standard dissolution equilibrium constant of it. Based on these results, three thermodynamic parameters of nano-CdS were calculated by introducing interface constants into the nanosystem.…”

Dissolution and Phosphate-Induced Transformation of ZnO Nanoparticles in Synthetic Saliva Probed by AGNES without Previous Solid–Liquid Separation. Comparison with UF-ICP-MS

“…37 An important advantage of AGNES is that it can be applied directly to the dispersion without the need of any previous solid/liquid separation step. 14,15 In this way, it allows a good control over the environmental variables (pH, temperature) as well as a relatively short time of analysis, which is essential for the measurement of dissolution rates. However, up to date, no direct experimental comparison between AGNES and other separation/analysis coupled protocols has been reported.…”

“…Different separation techniques have been proposed in the literature for this purpose. [13][14][15] One of the most common methods is ultrafiltration (UF), which involves the use of semipermeable filters (typically having pore sizes of 3 kDa) in a centrifugation tube.…”

“…The investigation of the dissolution of nanomaterials is often complicated by the necessity of a solid–liquid separation step before elemental analysis. Different separation techniques have been proposed in the literature for this purpose. − One of the most common methods is ultrafiltration (UF), which involves the use of semipermeable filters (typically having pore sizes of 3 kDa) in a centrifugation tube. The filtrate collected after centrifugation is analyzed subsequently by a suitable technique such as inductively coupled plasma-mass spectrometry (ICP-MS). , Even though UF is an affordable and robust technique, the use of an additional separation step in the analysis procedure adds a potential source of contamination and/or loss of analyte and increases the time required for sample pretreatment, which can be particularly important if the rate of dissolution is to be tested.…”

Dynamics of trace metal sorption by an ion-exchange chelating resin described by a mixed intraparticle/film diffusion transport model. The Cd/Chelex case

“…Consequently, this kind of resins has found numerous applications in different fields, such as DNA purification [1], removal of hazardous materials from wastewater [2,3], recovery of precious metals from leachates [4], chemical speciation studies in environmental matrices [5][6][7][8][9], or extraction and preconcentration of ions of analytical interest [10] for e.g. the determination of nanomaterial solubility [11].…”
