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.

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

polyacrylamide high purity pam powder,polyacrylamide emulsions and powders handling of emulsions using pumps is simpler than powders and in many cases, in-line injection can be used, avoiding the need for an aging tank. furthermore, dissolution times are much shorter and there are almost no solubility problems. unlike powders, emulsions are complex multicomponent products which include

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

preparation and properties of cationic polyacrylamide,cationic polyacrylamide is commonly used as a flocculant in the water treatment process in industries of mining, metallurgy, textile, papermaking and so on. It is also a multipurpose chemical used in oil industry.nano-silica/cationic polyacrylamide (cpam) prepared by inverse emulsion polymerization of modified silica (c-sio2) as a hydrophobic component with acrylamide, dimethyl diallyl ammonium chloride and methacryloyloxyethyl trimethyl ammonium chloride (dmc

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.

coagulation-ultrafiltration efficiency of polymeric al-, fe.polyacrylamide (pam) is a commercial polymer flocculant and widely utilized as a coagulant aid. the coagulation-flocculation mode combines the advantage of inorganic coagulant and organic flocculant, consequently elevating the removal efficiency and improving floc polyacrylamide flocculant.

chemical polyacrylamide water treatment polymer

polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. even though these products are often called ‘polyacrylamide’, many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof. these copolymers have modified

polymers emulsions and powder coagulant aids,anionic polymers produce a negative charge ion where as cationic polymers produce a positive charge ions when dissolved in water. most particulate matter/non-settling matter in surface water carry a negative charge, the addition of a positively charged coagulant such as alum will neutralise the particles allowing them to floc together.
