Solomon, Douglas Kip | Tracer applications of noble gas radionuclides in the geosciences | Noble gas radionuclides, including 81Kr (t1/2 = 229,000 yr), 85Kr (t1/2 = 10.8 yr), and 39Ar (t1/2 = 269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes. Recent advances in Atom Trap Trace Analysis (ATTA), a laser-based atom counting method... | | 2014-01-01 |

Solomon, Douglas Kip | Persistence of artificial sweeteners in a 15-year-old septic system plume | Groundwater contamination from constituents such as NO3 -, often occurs where multiple sources are present making source identification difficult. This study examines a suite of major ions and trace organic constituents within a well defined septic system plume in southern Ontario, Canada (Long Poin... | | 2013-01-01 |

Miller, Jan D. | Understanding the role of ion interactions in soluble salt flotation | There is anecdotal evidence for the significant effects of salt ions on the flotation separation of minerals using process water of high salt content. Examples include flotation of soluble salt minerals such as potash, trona and borax in brine solutions. Although some of the effects are expected, so... | | 2011-01-01 |
