“…FT-NIR techniques are also frequently used to monitor wastewater treatment processes. The parameters usually evaluated by this technique include polyhydroxyalkanoates, extracellular polymeric substances, biochemical oxygen demand, chemical oxygen demand, total suspended solids, total organic and inorganic carbon, bicarbonate alkalinity, biochemical methane potential, volatile fatty acids, nitrate, ammonia [19] and volatile organic pollutants as tetrachloroethylene and dichlorobenzene ( [20,21]) and fenitrothion [22]. However, the quantification of pharmaceuticals in wastewaters by FT-NIR is a field to explore and, to the authors' knowledge, no relevant works exist in the literature describing the use of this technique at this level.…”
