Alkaline chlorination
WebAs with alkaline chlorination, the product of the H2O2 reaction is cyanate (CNO-) which is 1,000 times less toxic than cyanide, and is often acceptable for discharge. Alternatively, cyanate can be destroyed through acid hydrolysis, forming carbon dioxide and ammonia. The equation is: CNO - + 2H 2 O → CO 2 + NH 3 + OH - (acid) WebShock chlorination is a process used in many swimming pools, water wells, springs, and other water sources to reduce the bacterial and algal residue in the water.
