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.

Refractive index increment of polyacrylamide flocculant,when treating the sewage with polyacrylamide polyacrylamide aqueous solution, first add 1ml aqueous solution in 100ml sewage to see the sedimentation flocculation effect, and then reduce or increase the dosage as appropriate.

optical constants of polyacrylamide solution in infrared

optical constants of pam solution. the optical constants of pam solution are obtained by the inversion model based on the experimental transmittance of pam solution. its concentrations are 20 mg/l, 80 mg/l, 100 mg/l, 400 mg/l and 800 mg/l, and the path length is 0.025 mm. the absorption index k and refractive index n in the wavenumber range of

optical constants of polyacrylamide solution in the infrared,the k-k relation is a process that obtaining the refractive index n in the case when the absorption index k is known. the complex optical constants of pam solution are defined by n ˆ (λ) n (λ) + i k (λ) where, n ˆ is the complex refraction index. λ is the wavelength. the real part of the complex refractive index is the usual

great strides in the development of high refractive index

in all the applications, these devices utilize high refractive index polymers (hrips) to control light. in general, the optical properties of transparent hrips enable efficient light transmission and manipulation, allowing optoelectronics devices to guide and control the flow of light to improve their performance.

polymer based flocculants review of water purification,examples of some of the findings in the literature on the subject of using polymer flocculants are: anionic flocculant is more effective at increasing the settling speed of slurries than cationic and non-ionic flocculants; when the ph, flocculant dosage, and shear rate rose, the relative flocculation rate increased at first and subsequently

water soluble polymer flocculants synthesis

in addition to the rate of polymer adsorption and particle collisions, the rate at which the adsorbed polymer chains relax on the particle surface (eventually forming a flattened conformation) is crucial in determining the extent of flocculation, defined by gregory as equilibrium and nonequilibrium flocculation. 9 in the latter, the adsorbed polymer is still extended when particles collide
