Figure 3. Free chlorine decay curves in seawater with different TOC and initial chlorine concentration.
Each line represents the predicted concentration of chlorine under a given condition. (a) Artificial
seawater solution with 1 mg L−1 of TOC; (b) artificial seawater solution with 2 mg L−1 of TOC; (c)
artificial seawater solution with 3 mg L−1 of TOC; (d) West Sea water (1.3 mg L−1 of TOC).
