摘要
采用水热法制备竹生物炭,用共水热和浸泡等方式对竹生物炭进行改性,并研究改性样品对盐酸四环素的吸附性能.实验结果显示,水热后经NaOH浸泡的样品对盐酸四环素的吸附性能最强,在盐酸四环素浓度为280 mg/L时,吸附量达到20.86 mg/g.经NaOH浸泡后改性样品的吸附过程符合Freundlich模型.
Bamboo biochar was prepared by hydrothermal method and modified by co-hydrothermal method and immersion.Then the adsorption property of samples for tetracycline hydrochloride was studied.The results show that the bamboo biochar immersed by NaOH solution has the strongest adsorption capacity for tetracycline hydrochloride.The adsorption capacity reached 20.86 mg/L when the concentration of tetracycline hydrochloride was 280 mg/L.The adsorption process of sample modified by NaOH immersion fitted the Freundlich model.
