Sonochemical degradation of azithromycin in aqueous solution
Background: The presence of pharmaceutical substances and their residual in water resources is an important environmental concern. Azithromycin, an antibiotic that is used for the treatment of infectious diseases, is a pollutant agent in the wastewater. The aim of this study was to investigate azithromycin degradation in aqueous solution through ultrasonic process in the presence of zinc oxide ...
متن کاملAmino Acids in Aqueous Solution
In the previous chapter, the focus was mainly on the behavior of ions in solution. The effect of concentration, solvent, as well as pH have been investigated; furthermore, alkali metal ions as well as transition metal ions have been studied. In this chapter, the investigation will be extended from ions to molecules, more specifically toward the behavior of amino acids in solution. Amino acids a...
متن کاملSucrose diffusion in aqueous solution
The diffusion of sugar in aqueous solution is important both in nature and in technological applications, yet measurements of diffusion coefficients at low water content are scarce. We report directly measured sucrose diffusion coefficients in aqueous solution. Our technique utilises a Raman isotope tracer method to monitor the diffusion of non-deuterated and deuterated sucrose across a boundar...
متن کاملGamma-radiolysis of aqueous solution of proline.
Gamma-radiolysis of 0.05 M neutral proline solution was investigated. As the main reaction of proline radiolysis in oxygenated solutions, the hydroxylation reactions leading to hydroxyproline formation and the reactions leading to the total destruction of the pyrrolidine ring were shown. In oxygen-free solutions the yield of these reactions decreased; in this medium combination reactions giving...
متن کاملGamma-radiolysis of aqueous solution of histidine.
The dependence of Gi(-M) values of histidine on the concentration of irradiated 10(-4) - 10(-1)M solutions, pH and the presence of O2, N2O and sec-butyl alcohol was investigated. In oxygen-free medium the maximum radiation sensitivity of histidine was found at pH 5--8; in oxygenated solutions it was shifted to the 6--1 pH range. The formation of radiation products was also studied. The course o...
