| Popis: | This study investigated the adsorption and migration characteristics of four sulfa antibiotics, which had been detected in the soil and groundwater in the northeast of China, namely sulfathiazole (ST), sulfamethyldiazine (SM), sulfamethazine (SM2), sulfamethoxazole (SMX); the groundwater pollution index was calculated by EPI Suite. Experimental results showed that the sulfa antibiotics have strong ability of migration, which was in the order of SMX > SM > SM2 > ST, and the content of sulfa antibiotics which passed through the zone of aeration and then entered the aquifer is above 78 %. Fe3+, Mn2+, iron oxide, manganese oxide and humic acid had a positive effect on the adsorption of sulfa antibiotics. The purpose of this study was to provide a scientific basis for removing the antibiotics in the soil and water. |
