Hydrogen peroxide industrial environment

The most commonly used technique for the determination of hydrogen peroxide in an industrial environment is the classical manual titration of a bath sample with potassium permanganate after acidification with sulphuric acid. In the past, numerous attempts have been made to perform the determination by means of an instrumental technique however, disadvantages were always encountered, which, up to now, have hindered the breakthrough of an alternative method. 

The application of hydrogen peroxide for environmental clean-up has a pivotal role to play within the chemical industry. Indeed, such treatments have breathed new life into industries which have been classed as damaging to the environment, thus extending their lifetime. Whilst it will always be desirable to aim for zero effluent processes, it is only realistic to have in the armoury the ability to treat waste products end of pipe . Such end of pipe applications for peroxy-gens will enable more economic routes to industrially important products to be developed. 

The use of hydrogen peroxide in pulp bleaching is now in widespread use as the industry strives to eliminate chlorine from the bleaching process. This has arisen over environmental concerns about organochlorine compounds being discharged into the environment, which are produced as by-products in chlorine bleaching processes.
