Decontamination of radioactive wastewater by two-staged chemical precipitation

[Decontamination of chemical warfare agents by photocatalysis].

Photocatalysis has been widely applied to solar-energy conversion and environmental purification. Photocatalyst, typically titanium dioxide (TiO(2)), produces active oxygen species under irradiation of ultraviolet light, and can decompose not only conventional pollutants but also different types of hazardous substances at mild conditions. We have recently started the study of photocatalytic dec...

Treatment of high boron concentration wastewater by chemical oxo-precipitation (COP) at room temperature

Chemical oxo-preceipitation (COP) process that combined the oxidant treatment and precipitation using metal salts was developed for boron containing water disposal under relatively milder conditions (room temperature, pH 10) than a precipitation process. Among the selected boron compounds in 1000 mg-B L, including boric acid (H3BO3), metaborate (NaBO2), borax (Na2B4O7) and perborate (NaBO3), th...

Modeling assessment for ammonium nitrogen recovery from wastewater by chemical precipitation.

Chemical precipitation to form magnesium ammonium phosphate (MAP) is an effective technology for recovering ammonium nitrogen (NH4(+)-N). In the present research, we investigated the thermodynamic modeling of the PHREEQC program for NH4(+)-N recovery to evaluate the effect of reaction factors on MAP precipitation. The case study of NH4(+)-N recovery from coking wastewater was conducted to provi...
