摘　　要：研究了以膨胀石墨(250 mL/g)为吸附剂,对活性艳红X-3B染料的吸附脱色作用,探讨了影响吸附的因素,结果表明:膨胀石墨对活性艳红X-3B染料的吸附率高,当膨胀石墨用量适当时,低初始浓度、低pH值有利于活性艳红X-3B染料的吸附脱色,温度高低对活性艳红X-3B染料的吸附脱色无明显影响。The adsorption and discoloration of reactive brilliant red X-3B were studied with the expanded graphite and its influencing factors were explored.The results showed that adsorption rate of the reactive brilliant red X-3B with the expanded graphite was high when the expanded graphite amount used was big.The low initial density and the low pH were in favor of the discoloration,but the temperature had no much affection to the discoloration.

关 键 词：膨胀石墨 活性艳红X-3B 吸附 脱色
