fabricating an anionic polyacrylamide (apam) with an anionic

in addition to flocculant dosage, the effects of ph on turbidity removal, zeta potential, and floc size were investigated at the optimal dosage of 0.8 mg l −1, and the results were shown in fig. 10. it was more clearly that the four flocculants displayed a similar flocculation variation tendency under various ph values (ph: 1.0–11.0).

review of polymers and coagulants used for flocculation of sale,the starch-based cationic copolymer has shown better flocculation performance compared to commercially available coagulants in the market for thick drilling fluid waste. a composite of organic and inorganic compounds was used as a flocculants for solid/liquid separation of discarded drilling fluid [ 20 ].

evaluation an anionic polyacrylamide flocculant with low cost

the slightly chemical shift of those two peaks at apam and apam-t polymer, which compared with pam were attributed to the different chemical environment. meanwhile, the absorption peak at δ 2.92 ppm was related to the proton of –ch 2 so 3 group. these indicated that the apam and apam-t polymers were composed of am and sas monomers.

recent achievements in polymer bio-based flocculants for sale,the flocculants, designed for coal slime water treatment, were characterized using the ftir, xrd and sem methods. it has been shown that water turbidity was reduced by ~97% and ~94%, while cod removal was ~78 and ~74% in the presence of fe 3 o 4 -chitosan-cellulose and fe 3 o 4 -chitosan-biochar, respectively.
