摘要： A method of continuously sampling and detecting a presence of selenium within water includes extracting an aqueous sample from a source of water, conditioning the aqueous sample within a conditioning unit to form a conditioned sample, where the conditioning includes providing the aqueous sample to the conditioning unit, combining a conditioning solution with the aqueous sample, where the conditioning solution comprises a combination of an oxidizing agent comprising nitric acid and a reducing agent comprising hydrochloric acid, and heating the sample combined with conditioning solution at a sufficient temperature and for a sufficient time period to convert selenium and/or selenate within the sample to selenite. The method further includes detecting a concentration of selenite in the conditioned sample within a detection unit.
