Abstract:Rhodamine WT (RWT) is an adsorptive flourescent dye tracer that is used in hydrological and hydrogeological studies. Municipal biosolids (sewage) are rich in organic matter and have a variety of chemical constituents that can interact to confound optical sensing of RWT florescence in water (e.g., quenching, interference, adsorption). Laboratory studies were conducted to evaluate optical sensing constraints associated with quantifying known RWT concentrations in a suite of RWT-spiked distilled water/liquid muni… Show more
“…This percentage likely reflects the tendency for RWT to sorb to the solid phase of the manure (Edwards et al, 2011). Both the liquid and solid components of the LSM were analyzed for 15 antibiotic compounds (Table 2), of which two are parent compounds (TY and CTC) administered in the feed.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
