Perchlorates—inorganic compounds carrying the perchlorate ion (ClO4)—were discovered at the north polar landing site of the Phoenix spacecraft and at the southern equatorial landing site of the Curiosity Rover within the Martian soil at levels of 0.4–0.6 wt%. This study explores in laboratory experiments the temperature-dependent decomposition mechanisms of hydrated perchlorates—namely magnesiu...

Kaur, Simran. M.S., Purdue University, December 2013. Chlorine Dioxide Gas Treatment of Cantaloupe: Residue Analysis. Major Professor: Mark Morgan. Chlorine dioxide (ClO2) is a selective oxidant and powerful antimicrobial agent. Previous work has shown that treatment of cantaloupe with ClO2 gas at 5 mg/L for 10 minutes results in a 4.6 and 4.3 log reduction of E. coli O157:H7 and L. monocytogen...

Abstract. Previous studies have established links between biodiversity and soil geochemistry in the McMurdo Dry Valleys, Antarctica, where environmental gradients are important determinants of biodiversity. However, these not well central Transantarctic Mountains, which thought to represent some least hospitable Antarctic soils. We analyzed 220 samples from 11 ice-free areas along Shackleton Gl...

This study evaluated the feasibility of electrooxidation process using a sub-stoichiometric titanium oxides (TiOX) reactive electrochemical membrane (REM) as anode for treatment secondary effluent from wastewater plant. The main objectives were to analyze (i) degradation pharmaceutical pollutant, carbamazepine, added at concentration 100 µg L−1, (ii) mineralization residual total organic carbon...

Swimming pool water treatment in general includes flocculation, sand filtration and subsequent disinfection. Chlorite, chlorate and bromate are disinfection by-products of swimming pool water treated by chlorine species or ozone. They are responsible for adverse effects on human health and their analyses in swimming pool water are necessary. The simply and fast suppressed ion chromatography sim...

Theoretical ab initio quantum mechanical charge field molecular dynamics (QMCF MD) has been applied in conjunction with experimental large angle X-ray scattering (LAXS) and EXAFS measurements to study structure and dynamics of the hydrated oxo chloro anions chlorite, ClO2(-), chlorate, ClO3(-), and perchlorate, ClO4(-). In addition, the structures of the hydrated hypochlorite, ClO(-), bromate, ...
