Metal-organic frameworks for water adsorption applications in the automotive filtration industry
… herangezogen wurde. Die Analytik wurde mittels Karl-Fischer Titration duchgeführt. MOF Materialien wurden in beiden Fällen mit kommerziell verwendeten Zeolithen und Silikagel verglichen.

High Temperature and High Pressure Determination of the Viscosity and Density of Bitumen as well as the Mutual Solubility of a Bitumen and Water Mixture
… and composition is determined from samples using Karl Fischer titration and Dean Stark distillation. Results indicate that density and viscosity decrease significantly with increasing temperature up to 300⁰C. Mutual solubility results were inconclusive due to apparatus malfunctions. Thermal …

Materials properties of pharmaceutical formulations for thin-film-tablet continuous manufacturing
… and SEM. Moisture content was measured out by Karl Fischer Titration and mechanical properties such as tensile strength were measured for all API/HPMC and placebo films. It was found that the mechanical and physiochemical properties of SPP-100/HPMC films were regarded as the most promising thin …

Colloidal microgels: synthesis, characterisation and applications
… content of biodiesel to an acceptable level. Karl Fischer titration results have shown that water level in biodiesel can be reduced below 500 ppm from 1800 ppm by using microgel as water absorbent. According to the EN14214 specification by European Committee 500 ppm is the maximum water level …

Developing analytical methods to determine physicochemical properties, protein and amino acid composition of African staple foods
… corn-soya and teff. Moisture was determined by Karl Fischer titration, and it was found that corn-soya, sorghum, maize, and teff had moisture levels below the recommended maximum limits. However, cassava revealed a high moisture content which would increase the risk of fungal contamination. …

Effect of water on copper electrodeposition from water-containing deep eutectic solvents
… water from the atmosphere was quantified using Karl Fischer titration. It was found that the electrolyte could incorporate water from 3 to 15 wt% over a month. Using these water amounts, the speciation of Cu (II) complexes, viscosity and conductivity were investigated. The behaviour of Cu (II) …

Electrolytic conductances and related properties of solutions of some acids and salts in acetone
… determination in acetone-was made. A modified Karl Fischer titration procedure was found to be most suitable for the very low moisture contents of the acetone used in this work. All A.C. conductance measurements made using two platinised electrodes are, in some degree, liable to errors due to …

Experimental Determinations and Modelling of the Viscosity of Multicomponent Natural Silicate Melts: Volcanological Implications
… 10 kbar. Water contents were measured using the Karl Fischer Titration (KFT) method. Fourier-Transform Infrared (FTIR) spectroscopy was used before and after the experiments in order to check that the water content was homogeneously distributed in the samples and that water had not been lost. …

Asset Management of Underground Cables Factoring Resilience
… by the New Zealand transmission company is the Karl Fischer titration test. This method is time-consuming and requires a fresh reagent for every test, and electrical power system companies, in most cases, have to send the test sample overseas to cable manufacturers or independent consulting …
