摘　　要：以负载TiO_2的颗粒活性炭为材料,去吸附紫色石蕊溶液,并通过介质阻挡放电的方式研究其再生,以TiO_2-GAC吸附紫色石蕊溶液的量来衡量再生的效率,通过改变放电频率、放电时间、放电极板间距与放电电压等方面对TiO_2-GAC再生情况进行探讨,定性地分析导致实验结果产生的可能原因。研究发现:放电电压为10 kV,放电频率为10 kHz,极板间距在10 mm,放电时间为40 min左右的情况下,TiO_2-GAC再生率达到72.7%,并且再生效率随着放电频率的增大而增大,还发现含水率和实验次数也会影响再生的效率。The regeneration efficiency was measured by the amount of TiO2-GAC adsorbed purple litmus solution.The efficiency of regeneration was measured by changing the discharge frequency.The discharge time,the discharge plate spacing and the discharge voltage and so on.The possible reasons for the experimental results were analyzed qualitatively.The results showed that the regeneration rate of TiO2-GAC was 72.7%.When the discharge voltage was 10 kV,the discharge frequency was 10 kHz,the plate spacing was 10 mm and the discharge time was about 40 min,and the regeneration efficiency increased with increasing of the discharge frequency.Results also showed that moisture content and the number of experiments would also affect the efficiency of regeneration.
