The synthetic organic polymeric flocculants, such as polyethyleneimine, polyvinylpyridinium salt, and polyacrylamide and its derivatives, have been reported in the flocculation treatment [8, 9]. However, the usage of synthetic organic coagulants could lead to secondary pollution in the drinking water thereby increasing the serious health risks,Processes | Free Full-Text | Preparation, Characterization Controlling the concentration of free radicals in polymerization systems is advantageous for preparing cationic polyacrylamide (CPAM) with a high molecular weight and acceptable dissolvability. In this study, a novel ultraviolet (UVA)-initiated system characterized by an adjustable light intensity and a redox-azo complex initiator was used to synthesize a CPAM flocculant named NP
Polyacrylamide
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1],5.5: Gel Electrophoresis of Proteins - Biology LibreTexts The gel matrix for gel electrophoresis of proteins. Gel electrophoresis of proteins almost exclusively utilizes polyacrylamide. This is a polymer comprised of two covalently-linked components: acrylamide; bis acrylamide. The bis acrylamide is essentially a cross-linking component of the acrylamide polymer.

Natural flocculants for the treatment of wastewaters
Besides, Yang et al. [121] have created a new chemically amphoteric bonded composite flocculant carboxymethyl chitosan-graft-polyacrylamide (CMC-g-PAM), synthesized and utilized to flocculate the kaolin particles for the treatment of water. The synthesis is carried out by the addition of monochloroacetic acid on the chitosan in order to modify,Comparison of adsorption affinity of anionic and cationic In the case of anionic polyacrylamide, the adsorbed amount decreases with the increasing pH. The pK a value of anionic PAM is equal to 3.2 and in the studied pH range the degree of carboxyl groups dissociation is from 98.7 to 99.8%. Therefore smaller adsorption of AN PAM at pH 7 is caused by unfavorable electrostatic repulsion between the
