Study on the Performance of Carbonized Diatomite Adsorption Treatment for Tetracycline Hydrochloride
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.
