摘　　要：研究海泡石对果糖的吸附性能,并与活性炭对其的吸附作对比。同室温条件下考察两种吸附剂的吸附时间、投加量对果糖去除率的影响。结果表明,海泡石的吸附效果明显优于活性炭,前者0.3 g几乎就可将50 mL 0.1 mg/mL标准液中果糖去除干净,而等量此标液,后者2.4 g才能达到最大吸附量,且果糖去除率只有前者的一半。综合考虑实际应用,获得了最佳吸附条件。The adsorption properties of sepiolite for fructose were investigated, comparing with activated carbon. The effects of adsorption time and dosage of adsorbents on the removal efficiency were studied at room temperature. The results showed that sepiolite was obviously superior to activated carbon on the adsorption ability. The dosage of the former was about 0. 3 g, removing fructose completely from 50 mL 0. 1 mg/mL standard solution. For the same amount of this standard solution, the maximum adsorbed capacity of the latter was about 2. 4 g, while the removal ratio was only half of the former. The optimum adsorption conditions were obtained.
