Abstract

Waste water generating in the production of ion exchange resins contains formaldehyde, chlorides and sulfates in its composition, exceeding the maximum allowable concentration, so there was a need to study various conditions of chlorides and sulfates content on the extraction of formaldehyde  from them. The existing thermal methods of sterilization of waste water during the production of ion exchange resins are not profitable  from an economic point of view, as there is the consumption of large quantities of natural gas, and formation of significant amount of highly mineralized concentrates. Thus, the development of water treatment method from formaldehyde,  based on chemical and physicochemical methods is an important issue. The article represents the results of studies of kinetic regularities of the interaction of carbamide with formaldehyde  in different ratios with different amounts of chlorides and sulfates, at different pH and temperature of solutions, generating during the production of ion exchange resins. The results can be used to assess the efficiency of waste water treatment from formaldehyde
