摘　　要：水体抗生素污染对自然环境和人体健康造成了极大的危害,本研究探讨活性炭和生物炭(秸秆炭、猪粪炭和竹炭)对水中四环素抗生素的吸附效果。结果表明:活性炭的吸附效果均优于其他三种生物炭,粉末活性炭的吸附表现优于颗粒活性炭,主要源于活性炭的比表面积和孔径远大于其他三种生物炭;随着吸附材料添加量的增加,吸附率均是逐渐增加,猪粪炭和秸秆炭对四环素的吸附率接近90%,仍低于活性炭的吸附率,生物炭在实际应用需要改性提高其对四环素的吸附效果。The antibiotics pollution on the environment and human health has greatly increased.Carbonaceous materials are often used to solve environmental pollution.Four carbonaceous materials were used as adsorbents to study the adsorption l properties of tetracycline antibiotics.The experimental results showed that activated carbon had more adsorption ability than the other three carbonaceous materials,the adsorption properties(both adsorption capacity and adsorption rate)of powdered activated carbon were better than the granular active carbon,due to their high specific surface area,abundant pore structure and strong interaction,the larger the dosage,the higher the removal rate,but the removal rate of the pig manure biochar and staw biocha was above 90%and still lower than the activated carbon,the biochar needed be modified during the pollution water treatment.
