The system features on-line Raman spectroscopy that quickly generates real-time data and analysis.

PNNL researcher, Samuel Bryan, says the monitoring system is capable of simultaneously and continuously quantifying the levels of all the chemically-significant anions within the waste, such as nitrate, nitrite, phosphate, carbonate, chromate, hydroxide, sulfate and aluminate.

The total sodium ion concentration was determined independently by modeling inputs from on-line conductivity and density meters.

The system is adaptable to monitoring in a variety of harsh environments. Bryan notes that system components and analytical tools of the process monitor can be tailored to monitor a variety of complex mixtures such as pulp and paper processing liquids, electroplating solutions, as well as radioactive tank wastes.
