Research Abstract |
Separation and recovery process of Tetramethylammonium hydroxide (TMAH), which is contained in waste solution from semiconductor or liquid crystal factories, are investigated based on adsorption technique. MCM-41 is used for the adsorbent. The adsorption properties of TMAH with MCM-41 have been investigated with batchwise adsorption. The chromatographic operation was also conducted to develop adsorptive separation process of TMAH, followed by granulation of MCM-41 with alumina-based binder.
