摘　　要：为了更好地去除水中抗生素污染,以盐酸四环素为去除目标,以D-无水葡萄糖为活化剂对硅藻土进行碳化改性,并探究其对盐酸四环素的吸附性能。对硅藻土改性前后进行表征测试以研究其表面形貌、化学性质与晶型结构的改变。改性后硅藻土表面更加粗糙且羟基等含氧官能团明显增加。通过吸附实验探讨了吸附温度、体系pH、盐酸四环素初始浓度和吸附剂投加量等因素对吸附量的影响。In order to better remove antibiotic contamination in water,tetracycline hydrochloride was used as the adsorbate,and D-glucose anhydrous was used as the activator to modify diatomite by carbonization,and its adsorption performance for tetracycline hydrochloride was investigated.Characterization tests were conducted on diatomite before and after modification to study the changes in its surface morphology,chemical properties,and crystal structure.The surface of modified diatomite was rougher and the oxygen-containing functional groups such as hydroxyl groups increased significantly.The adsorption experiments explored the effects of adsorption temperature,system pH,initial concentration of tetracycline hydrochloride,and adsorbent dosage on the adsorption capacity.
