Abstract

The reduction capacity of AMMONIA while present even at ppm level can be demonstrated by the increased encounter probability between AMMONIA and METHYLENE BLUE dye (MB+) incorporated in nanomordenite and Na-MOR ZEOLITEs. The rate of reduction METHYLENE BLUE dye by AMMONIA on the surface nanomordenite ZEOLITE is faster than Na-mordenite (Na-MOR) ZEOLITE.Because nanomordenite ZEOLITE with high silica (Si/Al=15) and surface area 400 (m2/g) is referred to as hydrophobic support with respect to Na-MOR ZEOLITE (Si/Al=6.5). On the other hand, the rate of color bleaching of MB+ by AMMONIA was found to be fastest in proton form of nanomordenite and mordenite ZEOLITEs. The results obtained with the ZEOLITEs were also compared with non-ionic micelle (TX-100). The calibration graph is valid for wide range of concentrations in nanomordenite ZEOLITE. The limit of detection (LOD) is 0.12 mg ml-1. This method is simple, sensitive and easy to carry out. By using only a UV-VISible spectroscopy, AMMONIA can be quantified.
