Vf. Kurenkov et al., Preparation of anionic flocculant by alkaline hydrolysis of polyacrylamide(Praestol 2500) in aqueous solutions and its use for water treatment purposes, RUS J AP CH, 74(3), 2001, pp. 445-448
A study was made of the low-temperature hydrolysis of high-moleculer-weight
polyacrylamide Praestol under the action of NaOH in dilute aqueous solutio
n. The performance of the hydrolyzed and nonhydrolyzed polymer when combine
d with aluminum sulfate in treatment of natural water was estimated.
