- In order to improve the recovery rate of sulfonamide antibiotics in sludge, and to optimize the extraction and determination methods of sulfonamides antibiotics in sludge, ultrasonic solid phase extraction -HPLC was used for the detection of sulfonamides antibiotics in sludge. First the determination of the test factors by single factor test was conducted, then the extraction conditions were optimized by orthogonal experiment. When the extraction ratio of V (acetonitrile): V (water) was =1: 3, oscillation time was 20 min, ultrasonic frequency was 35 Hz, ultrasonic time was 15 min, and extraction agent was 20 ml, when the average content of extraction of sulfonamide antibiotics reached maximum, the recovery rates of Sulfadiazine, and sulfamethazine antibiotics were: 75.50% and 72.79% respectively. This indicates that the detection method can determine the content of sulfonamide antibiotics in the sludge effectively.
