The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

| dc.description.abstract | The boron and sulfur isotopic ratios of four coal samples and corresponding fly ash leachates provide explanations for boron and sulfur incorporation into coal and behavior during combustion. Fractionation processes occur during coal formation and during the combustion of coal as some of the boron and sulfur is concentrated on the ash, and some escapes into the atmosphere as flue gas. Water-soluble boron in coal is extracted using a modified soil technique. Boron is isolated from solution using Amberlite IRA-743 resin and concentrated by methyl borate distillation with no isotopic fractionation observed. The forms of sulfur in coal are extracted sequentially using the lithium aluminum hydride (LAH) method. The isotopic content of samples from a coal-fired power-plant are used to determine if waste water has impacted a shallow aquifer system. No indication of mixing between waste water and ground water was observed. | |
