Pollutants, in waste water

It has been stated that the global LSER equation (eq. 1.55) takes into consideration simultaneously the descriptors of the analyte and the composition of the binary mobile phase and it can be more easily employed than the traditional local LSER model [79], The prerequisite of the application of LSER calculations is the exact knowledge of the chemical structure and physicochemical characteristics of the analyses to be separated. Synthetic dyes as pollutants in waste water and sludge comply with these requirements, therefore in these cases LSER calculations can be used for the facilitation of the development of optimal separation strategy.

CO2 hydrogenation, ammonia synthesis, hydrogenation of unsaturated organics, methane reforming, hydrogenolysis of saturated hydrocarbons, and wet oxidation of pollutants in waste waters have been tested, the main reactions taking place in the auto-exhaust converters have received special attention. Such is the case of CO and hydrocarbon oxidations, NO reduction, steam reforming, and water-gas shift reaction.

Mercury is one of the most toxic pollutants in waste waters. It can be detected by virtue of its static quenching effect on the fluorescence of indoles. When indole-3-acetie acid is covalently linked via long spacer groups to quartz beads welded to the tip of a quartz fiber or onto a quartz slide, its fluorescence (occurring at 350 nm) is quenched by mercury(II). Thus, the emitted light provides a continuous and reversible signal for the mercury (II) concentration of the solution in contact with the fiber end [19]. Mercury(II) concentrations down...
