15 صفحه اولSorption of Emerging Organic Wastewater Contaminants to Four Soils
Conventional onsite wastewater treatment system design relies on a septic tank and soil treatment unit (STU) for treatment of wastewater and integration of the final effluent into the environment. Organic water contaminants (OWCs), chemicals found in pharmaceutical drugs, detergents, surfactants, and other personal care and cleaning products, have been observed in septic tank effluent and the e...
متن کاملRedox and Sorption Reactions of Iodine and Cesium During Transport Through Aquifer Sediments
Radioactive isotopes of iodine (I and I) and cesium (Cs) are important contaminants present in nuclear waste. These radioisotopes have been introduced into the environment through nuclear weapons tests as well as nuclear accidents such as Chernobyl. Although iodine is commonly found as iodide (I), which is generally considered to behave conservatively, it has been proposed that iodide can be ox...
متن کاملNUREG/CR-6977, "Redox and Sorption Reactions of Iodine and Cesium During Transport Through Aquifer Sediments"
Radioactive isotopes of iodine (1311 and 1291) and cesium (137Cs) are important contaminants present in nuclear waste. These radioisotopes have been introduced into the environment through nuclear weapons tests as well as nuclear accidents such as Chernobyl. Although iodine is commonly found as iodide (F), which is generally considered to behave conservatively, it has been proposed that iodide ...
متن کاملEvidence of micropore filling for sorption of nonpolar organic contaminants by condensed organic matter.
Although microporosity and surface area of natural organic matter (NOM) are crucial for mechanistic evaluation of the sorption process for nonpolar organic contaminants (NOCs), they have been underestimated by the N adsorption technique. We investigated the CO-derived internal hydrophobic microporosity () and specific surface area (SSA) obtained on dry samples and related them to sorption behav...
