The influence of change of temperature on the carbonic acidbase-protein equilibrium in blood or serum involves three factors: (1) Change in solubility of CO2 in serum or blood. (2) Change in the equilibrium constants of the buffer systems in the blood. (3) Change in the equilibrium constant for the dissociation of water. The fact that the solubility of CO2 changes with temperature has naturally...

background: in recent years, various toxic chemicals/compounds have been widely detected at dangerous levels in drinking water in many parts of the world posing a variety of serious health risks to human beings. one of these toxic chemicals is lead, so this paper aimed to evaluate of efficiency coconut husk as cheap adsorbent for removal lead under different conditions. methods: in the spring o...

background & aims of the study: dyes are one of the widespread chemicals which may have many adverse effects on life cycle. thus, this study was conducted to survey the rb19 dye removal efficacy from aqueous solution, using the sio2 nanoparticles. materials and methods: this study was an experimental-lab study. the batch adsorption system were utilized to evaluated the rb19 dye removal efficien...

The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...

isotactic poly (1-butene), ipbu-1, was synthesized by using a metallocene catalyst. the thermodynamic phase behavior of polymer–organic solvents systems is very important in every polymer application.  in this paper, the solid–liquid equilibrium of ipbu-1 with different organic solvents (1-heptyne, cyclo octane) was studied by a mathematical model. by considering the experiments temperature-mol...

Detecting the passage of an interfering particle through one of the interferometer's arms, known as "which path" measurement, gives rise to interference visibility degradation (dephasing). Here, we consider a detector at equilibrium. At finite temperature, dephasing is caused by thermal fluctuations of the detector. More interestingly, in the zero-temperature limit, equilibrium quantum fluctuat...

Natural gas sweetening is an important process which is used for treatment of sour gases. The measurement of solubility is also considered in most sweetening processes such as that of Townsend process. Therefore, experimental measurements would be helpful to determine the equilibrium data under actual equilibrium conditions for the gas treatment plants. In this research solubility of hydrogen s...
