Acid hydrolysis reaction of polyacrylamide and its ...

After the elimination of ammonia (NH3), the structural unit of the acrylamide is hydrolyzed to the acrylic ,acid, structure unit. The viscosity and ,pH, value of the aqueous solution can be changed with the hydrolysis. In the reaction liquid ,PH, < 8 ,without, a buffer, ammonia becomes the solution ,pH, increases, the viscosity increases.

Neutralization may be used to treat ,acid, wastewaters containing metals. Adding an alkaline reagent increases the ,pH, of the ,acid, waste. This forms a precipitate that collects unwanted metals. The result is an incoming solution of which the ,pH, has been adjusted to the optimum range for precipitating metals as …

4/4/2016, · However, Hao et al. indicated that struvite could get the highest purity at ,pH, = 7.0, and the purity seemed to have fallen with the increasing of the ,pH, value of ,wastewater,. When the value of ,pH, is higher than 10, the formed precipitate mainly consists of Mg 3 (PO 4) 2 (K sp = 9.8 × 10 −25).
