uses of high purity polyacrylamide degradation and its implications

Chemical and photolytic degradation of polyacrylamides used in potable water treatment

PAMs have been used in drinking water treatment as flocculants or coagulants in the highest volume among all the polymer types. In potable water treatment processes, polyacrylamides are often exposed to oxidants (e.g. chlorine and permanganate)
