How to Use Polyacrylamide for Water Treatment, Polyacrylamide Flocculant, Cationic & Anionic Polyacrylamide | YrdCarbon,Polyacrylamide (PAM) is a type flocculant of polymer that is soluble in water, and it is formed through acrylamide polymerization. It can be adjusted for use in a wide range of applications. This type of polymer is produced and sold in different forms, which include cationic polyacrylamide, anionic polyacrylamide, and non-anionic.
Influence of surfactants on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (PAM-C) flocculant
This paper reports the result of studies on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (PAM-C) flocculants in presence of surfactants. The surfactants used were namely anionic sodium dodecyl sulphate (SDS), cationic cetyl trimethyl ammonium bromide (CTAB) and non-ionic TritonX 100, which is a polyoxyethylenic ether compound.
Comparison of adsorption affinity of anionic and cationic polyacrylamides for montmorillonite surface in the presence of chromium(VI) ions,The soil conditioners commonly used in agriculture is ionic polyacrylamide (PAM)¡ªboth anionic and cationic. These macromolecular substances affect soil surface properties and adsorption behaviour of substances present in the environment¡ªnutrients, organic molecules and also hazardous compounds as well as toxic heavy metals (i.e. chromium(VI) ions).

Introduction to Polyacrylamide Gels | Bio-Rad
Precast vs. Handcast Gels Format (Size and Comb Type) Polymerization Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).

Running agarose and polyacrylamide gels | IDT
Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1?1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.

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.
