Determination of performance indicators of PFS

Determination of performance indicators of polymeric ferric sulfate

(1) Density measurement
Measure the density of 20 ℃ polymeric ferric sulfate solution using a specific gravity meter with a measurement range of 1.400 g · mL to 1.500 g · mL.
(2) PH value determination
Measure the pH value of polymeric ferric sulfate using a pH meter.
(3) Viscosity measurement
Measure the viscosity of polymeric ferric sulfate in a constant temperature water bath at 20 ± 0.1 ℃ using a known viscometer constant and a capillary viscometer.
