Synthesis of a Micro-Crosslinked Polyacrylamide Flocculant and Its

Abstract A cationic polyacrylamide (PADO) with excellent flocculation performance was synthesized by the inverse emulsion polymerization of acrylamide benzyldimethyl [2- [ (1-oxoallyl)oxy]ethyl]ammonium chloride (DBC) and vinyl siloxanes (VTEO). The structure and weight of PADOs were characterized by H NMR spectra and static light scattering.

Water Soluble Polymer Flocculants: Synthesis, Characterization,

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Synthesis of crosslinked starch-graft-polyacrylamide-

This new flocculant on the basis of starch-graft-polyacrylamide-co-sodium xanthate (CSAX) is prepared by first cross-linking starch, in which epichlorohydrin (EPI) is used as the cross-linking regent, and then grafting polyacrylamide chains to crosslinked starch (CSt) by ceric ammonium nitrate (CAN) as an initiator, thus crosslinked starch-graft-polyacrylamide (CSA) is obtained, at last

Synthesis of a novel flocculant on the basis of crosslinked Konjac

A novel flocculant on the basis of crosslinked Konjac glucomannan-graft-acrylamide-co-sodium xanthate was synthesized by crosslinking KGM, using epichlorohydrin (ECH) as crosslinker, then grafting polyacrylamide chains to crosslinked KGM by ceric ammonium nitrate(CAN) as an initiator, then semi-manufactured goods, activated by NaOH, was xanthated by reacting with carbon disulfide.

Polyacrylamide and Chitosan Biopolymer for Flocculation

Erosion and sediment control using chemical flocculants has been used on construction sites around the United States, typically larger sites where there is a high potential of sediment pollution to waterbodies [1, 2]. The most common flocculant is polyacrylamide (PAM), but others such as biopolymers are also available [3,4,5].

Preparation of octopus-like lignin-grafted cationic polyacrylamide

However, the most commonly used organic synthetic flocculants such as polyacrylamide are petroleum-based. In this work, biomass lignin was grafted with cationic starch to synthesize low-cost, green and fully biomass-based multifunctional flocculants. The cationic polyacrylamide was replaced by cheap industrial cationic starch.
