| Popis: | 103 Due to laws added and the consciousness upgrade of environmental for industrial wastewater in the pollution materials control. How to avoid and protect our environment from the pollution of industrial wastewater? It is very important!! High concentrations of Tetramethylammonium hydroxide (TMAH) can be found in industrial wastewater from semiconductor manufacturing process. Tetramethylammonium hydroxide(TMAH) is highly toxic and corrosive, thus it have to be properly wastewater treatment processes are still not satisfactorily effective, which because oxide issue. Therefore resin is proposed to remove Tetramethylammonium hydroxide(TMAH) from wastewater ion exchange process. In this study, ion exchange of resin process using strong acid (SAC) cation exchange resin were used to remove TMAH from wastewater solution. The solution to showed high TMA+ ion could removal to 30 ppm. Investigation on the effect of pH and H2O2 concentration was more affected, so we setting monitor system to control resin efficiency. The showing a promising and efficient capability to remove and control TMAH from wastewater. |
