AB  - Industrial wastewater contains recalcitrant organic compounds with a very complex chemical structure, built of molecules with long chains of carbon atoms and attached different functional groups. Chemical or biological treatments used for removal of these compounds are being replaced with more efficient non-commercial wastewater treatments. Advanced oxidation processes overcome limitations of conventional methods regarding formation of by-products during degradation of recalcitrant organic compounds. The Fenton process, or use of the Fenton's reagent, has became one of the most utilized processes due to simplicity, economy and accessible amounts of ferrous iron and hydrogen-peroxide, which are used in the process. In specific, the Fenton's reagent is a catalytic-oxidative mixture of these two components. The ferrous iron Fe2+ initiates and catalyzes decomposition of H2O2, resulting in generation of hydroxyl radicals, which are the main radical species in the process able to detoxify several organic pollutants by oxidation. In addition, other mechanisms besides formation of hydroxyl radicals may occur during the Fenton process and participate in degradation of target pollutants. Generally, the treatment efficiency relies upon the physical and chemical properties of target pollutants and the process operating conditions. The main disadvantage of the Fenton process is production of sludge formed by iron hydroxide at certain pH values. An alternative solution for this problem is application of this process in fluidized bed reactors. This paper presents an overview of Fenton and photo-Fenton processes in dispersed systems for removal of different industrial wastewater pollutants. The most important process parameters, required for efficient degradation of recalcitrant organic compounds are also described, such as the catalyst type, pH value, temperature, H2O2 concentration and retention time. Strict control of Fenton process parameters in fluidized bed reactors at desired values can bring these systems to the commercial use.

AB  - The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and 0.83170), over the ionic strength range (2.4958 to 6.0801) mol.kg (1), using KCl(aq) and CaCl2(aq) as the reference standard solutions. These measurements include some new isopiestic results for the KNO3(aq) binary system extending slightly into the oversaturated (supersaturated) molality region from (2.1973 to 4.1295) mol.kg (1). Our new experimental results were modeled with an extended form of Pitzer's ion-interaction model equations, both with the usual Pitzer mixing terms and with Scatchard's neutral-electrolyte mixing terms, and with the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale. There are no previously published isopiestic measurements for the {yKNO(3) + (1 - y)K2HPO4}(aq) system. The present assessment yields NO3 - HPO42 mixing parameters for these models that are needed for modeling the thermodynamic activities of solute components of natural waters and other complex aqueous electrolyte mixtures. Model parameters for KNO3(aq) at T = (298.15 +/- 0.01) K were also evaluated using the present results along with critically-assessed osmotic coefficients taken from the published literature. Thermodynamic properties of the saturated solution were calculated using published solubilities of KNO3(cr) in water at T = 298.15 K and the evaluated ion-interaction model parameters for KNO3(aq).
