Selenium is becoming a priority pollutant in many parts of North America because of its high toxicity to aquatic wildlife. Many mining operations face extensive regulation with respect to their selenium discharges, which results from accidental mobilization during the respective mining process.
In all environmental and industrial processes, individual selenium species differ greatly in their behavior, so the determination of these individual species and their relative distribution is of critical importance. In lower concentrations, selenium is a necessary nutrient for the existence of life; however, at concentrations ten times the recommended dosage, selenium becomes a carcinogen with direct health impacts.
Methods for Selenium Speciation Analysis: Applied Speciation employs anion chromatography coupled with the detection power of our ICP-DRC-MS for Selenium Speciation Analysis. The Dynamic Reaction cell is used to eliminate the background signal from the plasma gas components allowing us to achieve detection limits around 10 ppt (ng/L). During Selenium Speciation Analysis, the species of interest are usually selenite (Se(IV)) and selenate (Se(VI)). Elemental selenium is usually mobilized by cyanide and therefore, the main species after mobilization is selenocyanate (SeCN) and selenate. Since selenocyanate can be present in many mining wastewaters, we have a method that includes SeCN in the separation scheme. Just like arsenic speciation, depending on the matrix, different analytical separation modes can be utilized for selenium speciation analysis to improve detection and/or eliminate certain interferences/problems.
