 en Removal of Urotropine from Industrial Wastewater by Acidic Cation Exchange Resins
Saadatjou, N.; Taghdiri, M & Farrokhi, R.

Abstract

The industrial wastewater produced by urotropine plants is considered as a major environmental polluting factor and hence its treatment is required. In this work, strongly acidic cation exchange resins including C100H (Purolite), Amberlite IR120 and Amberlyst 15W were used for removing of urotropine from wastewater. Optimum conditions for the three resins and regeneration were studied. The required amounts of resins for efficient exchange of urotropine and amount of acid for regenerating process of exhausted resins were determined and the potential of these resins in removing of urotropine and ammonia from the wastewater were compared. It was found that C100H resin has a higher capability in removing of urotropine in comparison with tow other resins. This capability of C100H was 2 and 7 times greater than Amberlite IR120 and Amberlyst 15W, respectively. The comparison of results with other methods indicates that this method reduces urotropine concentration more effectively. The simple and fast conductometric method has been developed for determination of urotropine in wastewater in the presence of formaldehyde and ammonia without any interference.
