Phase 2: establishing detection limits in different water matrices
Table 2 provides the detection limits measured at 191.5, 200, and 210 nm in different water matrices and with different polymers. The descriptions of the water and wastewater samples are provided in the Materials and Methods section.
Detection limits in centrate collected from a wastewater treatment plant
Known concentrations of polymers Hydrex 3572 and FloPolymer CB 4350 were spiked in centrate collected from Treatment Plant A
