【摘要】 本文研究了预吸附水对400℃活化的糖炭自水溶液中吸附酸(乙、丙、丁、戊酸,苯甲酸和盐酸)和硷(氢氧化钠和氢氧化桉)的影响。结果表明预吸附了水的糖炭对乙酸、丙酸和盐酸的吸附量有所增加,而对丁酸、戊酸、苯甲酸、氢氧化钠和氢氧化铵的吸附量则有所减少。这些结果虽具有一定的实际意义,但我们还不能提出合理的解释。更多还原

【Abstract】 Adsorption of some acids (acetic, propionic, butyric, valeric, benzoic and hydrochloric acids) and bases (sodium hydroxide and ammonium hydroxide) from water by sugar charcoal (activated at 400℃) in the absence or presence of pre-adsorbed water has been studied. Results show that the presence of pre-adsorbed water tends to increase the adsorption of acetic, propionic and hydrochloric acids, but decrease the adsorption of butyric, valeric and benzoic acids, sodium hydroxide and ammonium hydroxide. However, the results remain unexplained.更多还原
