  • 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.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • 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.
  • Is there a standard method for detecting dilute polyacrylamide in fresh water?
  • There is no standard method for detecting dilute polyacrylamide in fresh water due to the multiple challenges inherent in gaining the required sensitivity necessary to distinguish the hydrophilic polymer against the multitude of other environmental impurities possible within such a sample.
