Abstract The total phosphorus (TP) content of activated sludge was determined by an ultrasonic cracking assisted wet method. This study investigated the individual and interactive effects between three factors of sampling volume, sonication time, and sonication power, using the response surface methodology with the TP content as the response value, based on the single-factor test. Meanwhile, four sludge TP determination methods were compared, i.e., ultrasonic cracking wet method, microwave digestion method, SMT method, and improved national standard method. The results showed that the ultrasonic cracking wet method had the highest accuracy and stability in determining the TP content of sludge under the conditions of 15mL of sludge mixture sampling volume, 22min of ultrasonic time, and 720W of ultrasonic power. The results of the sludge TP determination followed the order of ultrasonic cracking wet method > microwave digestion method > SMT method > improved national standard method. There was a significant linear correlation between the ultrasonic cracking wet method and the other three methods (correlation coefficients of 0.9997, 0.9977, and 0.9969, respectively) with the fitted function slope values of 0.9436, 0.9183, and 0.8295, respectively. The RSDs for the determination results of TP in sludge samples by the ultrasonic cracking wet method were £3.6% and the spiked recoveries were 96.5%~104.8%. This study demonstrates that the ultrasonic cracking wet method is of good reliability, economy, and ease of operation in determining TP. Furthermore, ultrasound can save chemicals and extraction time.
