Effects of Cationic Polyacrylamide and Cationic Starch
In this study, the two components of a commercial flocculant block formulation, anionic polyacrylamide (PAM) and polyethylene glycol (PEG), and the flocculant block itself were assessed to determine which ingredient was most toxic, and to find safe concentration levels.,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],The new life of traditional water treatment flocculant Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.
Introduction to Polyacrylamide Gels
Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.,Agarose Gel vs. Polyacrylamide Gel: What’s the Difference?
Key Differences. Agarose gels are typically used in DNA and RNA electrophoresis due to their larger pore size. Polyacrylamide gels are preferred for protein electrophoresis and smaller nucleic acids, owing to their finer pore structure. This fundamental difference in pore size affects their respective uses in molecular biology.,Factory Price Anionic Polyacrylamide - Alibaba.com Source wholesale factory price anionic polyacrylamide quickly and easily with Alibaba.com.

Polyaluminium Chloride(PAC) water treatment agents
Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts.
