为了验证银杏活性炭的吸附效果,分别采用静态吸附法和动态吸附法,研究了银杏活性炭对部分有毒气体及铅、镉两种重金属离子的吸附作用.结果表明:银杏活性炭对甲醛、苯、氨气、三氯甲烷这4种气体的吸附能力都较强,其对甲醛的吸附能力最强.吸附率可达到140%;银杏活性炭吸附铅、镉离子的效果也较好,对铅离子的吸附量接近200 mg·g-1,对镉离子的吸附量能达到90 mg·g-1;银杏活性炭对铅、镉离子的吸附受振荡时间、离子浓度、pH值、离子竞争吸附等因素的影响,但温度对铅、镉离子的吸附没有显著影响.%To study the absorption effect of ginkgo activated carbon, using static and dynamic absorption methods, the adsorption of part poisonous gas and two heavy metals (Pb, Cd) in waste water was studied.The results showed that the ginkgo activated carbon had good adsorb ability to the four gases of formaldehyde, benzene, chloroform and ammonia, and the adsorbing rate of formaldehyde reached to 140％ formaldehyde, which was the highest.The adsorption of heavy metals on activated carbon was also fine, the absorptivity of Pb2+ and Cd2+ could reach to 200 mg·g-1 and 90 mg · g-1, respectively.The effects of shaking time, ion concentration, pH value and ion competitive absorption on the absorptivity of Pb2+ and Cd2+ were significant, but temperature.
