Fabricating an anionic polyacrylamide (APAM) with an anionic block

Flocculation experimental results demonstrated that the anionic microblocks in the template copolymer could enhance the charge neutralization and bridging ability, and therefore an excellent flocculation performance of treating high turbidity water was observed. 1. Introduction

Water Soluble Polymer Flocculants: Synthesis, Characterization,

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide, is highly water soluble, cost-effective, and very

Natural flocculants from fresh and saline wastewater: Comparative

EPS, being anionic polyelectrolytes have somewhat similar flocculation mechanism with synthetic anionic flocculants such as polyacrylamide. In sludges, EPS have been reported to cause bioflocculation via the divalent cation bridging (DCB) mechanism, whereby divalent cations such as Ca 2+ and Mg 2+ form bridges between anionic groups of EPS and negatively charged particles in sludge [19] .

Optimization of flocculation conditions for soluble cadmium removal

In this work, we describe a flocculation performance evaluation of a novel anionic polyacrylamide (APAM) synthesized using low dose ¦Ã-ray initiation. The APAM structure and morphology were characterized using Fourier transform-infrared spectroscopy (FTIR), High performance liquid chromatography (HPLC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) techniques.
