Figure Lengend Snippet: Concentration dependence of H 2 A on the DCLIU response observed in 0.1 M Na 2 CO 3 containing 10 μM luminol and 1 μM Co 2+ after irradiation with 1 MHz ultrasound for 5 s. The peak areas were determined by integrating the delayed chemiluminescence signal in Period II. Specifically, the integration time ranges were as follows: 65.06–532.42 s (10 nM), 58.03–612.49 s (30 nM), 69.81–734.02 s (50 nM), 85.73–808.21 s (70 nM), and 103.19–813.11 s (90 nM).
