The applicability of silver nitrate titration and potentiometric titration, two of the three detection methods for chlorine in food samples specified in the national standard GB 5009.44—2016, for infant formula for special medical purposes was evaluated. The results showed that the spiked recoveries of silver nitrate titration for partially hydrolyzed protein infant formula, extensively hydrolyzed protein infant formula, and amino acid-based infant formula for special medical purposes were 95%–108%, 98%–125% and 100%–106%, respectively, and the relative standard deviations (RSD) for precision were between 12.7% and 32.9%. The results of potentiometric titration was lower than that of silver nitrate titration.
