  • Which polyacrylamide polymers were tested with distilled water?
  • In the first phase of experiments, seven polyacrylamide polymers (Hydrex 3591, 3593, 3596, 3661, 3572, MagnaFloc LT 27AG and FloPolymer CB 4350) were tested with distilled water to establish their detection limits and characteristics of their UV absorbance spectra.
  • Can a UV spectrophotometer measure polyacrylamide concentration?
  • This study presents a method for quantification of polyacrylamide concentration using an in-line UV–vis spectrophotometer that can generate real-time data. Absorbance spectra of seven polymers were established in the wavelength range of 191.5–750 nm and the highest absorbance was recorded at 191.5 nm for all polymers.
  • Can a spectrophotometric spectrophotometer measure polymer concentration in water?
  • Recently, Gibbons and Örmeci [ 22] developed a spectrophotometric method to measure polymer concentration in water using a bench-top UV–vis spectrophotometer. UV–vis measurements are quick, simple, and accurate, and can find successful applications in research and industry.
  • Do polyacrylamide polymers absorb light?
  • The results from this study indicate that polyacrylamide polymers used for water and wastewater treatment strongly absorb light in the 191.5–230 nm wavelength range, and the peak absorbance was measured at 191.5 nm for all of the seven polymers tested in this study.
