【 摘 要 】

The goal of this work was to study the efficiency of ammonia adsorption of four white charcoals include Bamboo, Coconut spathe, Coconut shell and Miscellaneous woods. The ammonia 20 mL was used as the odour sample for adsorption, 0.1 grams of each white charcoal was used as adsorbent and adsorption time were studied in 20, 40, 60, 80, and 100 min. The gravimetric method was used as method for study ammonia adsorption. The results show all white charcoals have saturated adsorption in range 40-60 min. The sequent of ammonia adsorption with white charcoal from descending were Miscellaneous > Coconut spathe > Coconut shell > Bamboo. A statistical test with Paired Samples T-Test, the result of four white charcoal to absorb the odour of ammonia in the all adsorption times have difference statistically significant at the 95% confidence.
