The onset of COVID-19 pandemic has suddenly rendered disinfectants an essential class substances for daily use globally. demand different rapidly surged, and it is important that the users are aware chemicals present in them, their properties, how these were introduced public use. history development chlorine-containing possible modes action have been explained this article. current status hypo...

This innovative technology evaluation report (ITER) presents the evaluation of two field screening technologies for determining polychlorinated biphenyl (PCB) contamination in soil. The demonstration was conducted by PRC Environmental Management, Inc. (PRC), under contract to the Environmental Protection Agency’s (EPA) Environmental Monitoring Systems Laboratory-Las Vegas (EMSL-LV). The Clor-N-...

Changes in BET surface area and morphology of Ti02 (anatase) were studied as a function of temperature and level of chlorine contamination. The objective was to study the behavior of TiO2 supports under typical catalyst preparation and reaction conditions, using adsorption, wide angle X-ray diffraction and scanning electron microscopy. Chlorinated samples had lower surface areas compared to bla...

Poliovirus in fecal homogenates was used to determine the protection against inactivation by chlorination afforded virus that was occluded within particulates. Virus that was closely associated with or occluded within small fecal particulates was protected. A fourfold increase in combined residual chlorine was required to achieve the same degree of inactivation for occluded virus as for free or...

The influence of hydrazine reduction on metal dispersion, particle size distribution, and support morphology was investigated for a series of bimetallic Ru-AuiMgO catalysts. The catalysts were prepared by impregnation of MgO with chlorine-containing precursor salt solutions. Hydrazine reduction significantly lowered the residual chlorine content of the catalysts and allowed the formation of hig...
