Biodegradation of Polyacrylamide and Its Derivatives - Springer
Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007 ).,(PDF) Quantitation of acrylamide (and polyacrylamide
A statistical design kinetics model was constructed through second-order regression to predict the rate of polyacrylamide redox polymerization and the R-2 value was 0.9888, which fitted the,Poly-Aluminium Chloride (PAC) Description.

AN OPERATOR’S GUIDE TO WATER TREATMENT COAGULANTS
To calculate the dose of a coagulant or other chemical in mg/L, you will need to know its % w/w strength and specific gravity. The formula is: mg/L = 10,000 X % w/w X SG. For example, consider alum at 49 % w/w strength aluminium sulphate (as Al2(SO4)3.18H2O) and with a SG of 1.29.,Polyacrylamide Anionic polyacrylamides (aPAMs) are used in the construction field as a thickener or flocculent. Their chemical structure is shown in Figure 9.30. APAMs are synthesized by free radical polymerization of acrylamide and acrylic acid salts or by partial hydrolysis of non-ionic polyacrylamide (Cheng 2004; Bessaies-Bey et al., 2015).
PRODUCT DATA SHEET PAC Poly Aluminum Chloride
Poly Aluminum Chloride (PAC) is a water-soluble inorganic polymer used as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. 2. Application PAC is also used in a variety of other,Production of Poly(aluminum chloride) and Sodium Silicate Expand. 28. A novel process is proposed for the extraction of aluminum from clay, by which the aluminum is recovered as poly (aluminum chloride) solution requiring energy much less than that for the recovery as alumina, and the volume of the siliceous residue left after the aluminum was extracted from the clay can be reduced by 70% by
