polyacrylamide pam chemical water treatment

between suppliers etc. furthermore, slight differences in statistical distribution of molecular weight of the polymer and size of the beads of polymer may generate changes in the refractive index of the components and lead to slight color variations. color changes can also occur during the storage (due to temperature differences, uv

(pdf) refractive index increments of polyacrylamide for free sample,in the reported experiments, the refractive index increments of linear and branched polyethylene were determined for several solvents and various wavelengths (403, 436, 546, and 633 nm), mainly at

optical constants of polyacrylamide solution in the infrared

the range of absorption coefficient of pam solution is 15.90–31.11. the temperature has a great influence on the optical constants of pam solution. with the increase of temperature in the range of 20–70 °c, the absorption index of pam solution decreases gradually and the absorption index k range is 1.56e-3–5.83e-3.
