Determination of thermodynamic parameters of hydrogen permeation of palladium membrane for considering the effect of stainless steel support
A palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-PSS). Hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674K and the pressure difference of two sides of membrane up to 90kPa. A simplified resistance model was employed to analyze the permeation behavior of hydrogen through Pd/ox-...
متن کاملThermodynamic study of Cu(II) ion-selective membrane electrode based on his (N-salicylidene-3,32-diamino dip hen y sulfone
The effect or temperature on the behavior of Cu(II) Mr electrode based on bis(N-sahcylidenc-3.3'-4iaminodiphenyl) sulfune(BSDDS) was studied. This electrode showed a good Nemstian response in the temperaturerange of 20-50 C. Also, the behavior of the synthesized electrode was inngigated in the mixed solvents'ethanol+water" and "dioxane +water'.
متن کاملConstruction of S?-Selective Electrode and Thermodynamic Study of the Ternary Aqueous Mixed Electrolyte System (SrCl2, KG, H20) Using Potentiometric Method
In order to preparing strontium ion selective electrode 6-(4- nitropheny1)-2-pheny14, 4- dipropy1-3, 5-diaza-bicyclo [3, 1, 0] hex-2-ene (NPDBH) was used as an ionophore. This electrode responds to Sr (II)ion with a sensitivity of 28.2 ± 0.5 mV/decade over the range 1.0 x 10-6 to 1.0 Mat pH 3.0-10.0. Thelimit of detection was 2.4 x 10-7 M. The influences of membrane composition, the pH of the t...
متن کاملVariation of Immiscibility Gap in Polymer Solution Containing Alkane and Effects on Providing the Membrane
In oredr to reduce costs and save time for the membrane manufacturing process, it is necessary to improve the quality of membranes by modeling usage. In this study, Flory Huggins model was used to predict quaternary-system containing polyether sulfone, N-Methyl-2-pyrrolidone, water and used alkanes as an additive. Due to the solubility parameters and molar alkane volumes, the interaction parame...
متن کاملConstructal approach to cell membranes transport: Amending the ‘Norton-Simon’ hypothesis for cancer treatment
To investigate biosystems, we propose a new thermodynamic concept that analyses ion, mass and energy flows across the cell membrane. This paradigm-shifting approach has a wide applicability to medically relevant topics including advancing cancer treatment. To support this claim, we revisit 'Norton-Simon' and evolving it from an already important anti-cancer hypothesis to a thermodynamic theorem...
