摘 要：采用显色法分别检测分析了甲醛、双氧水在海水中的消解速率，其最低检出限分别为0.25 mL/m3和0.125 mL/m3；同时研究了两种消毒剂加入海水中对水质因子的影响。结果表明：这两种消毒剂的消解速率与其使用浓度密切相关，使用浓度越高，在海水中的消解时间越长。甲醛浓度在100 mL/m3时，48 h显示白浊，基本上降解消除；而当双氧水浓度在100 mL/m3时，96 h仍有较高残留。由此得出，相同浓度甲醛的消解速率比双氧水快得多。在1 500 mL/m3双氧水和600 mL/m3甲醛极高浓度下，7 d后仍保持着很高的残留量。海水中加入甲醛，溶解氧、盐度、温度、pH均没有显著变化（P＞0.05），而加入双氧水的海水，除了溶解氧提高以外（P

Abstract: This article analyzed the rate of decompound of formaldehyde and hydrogen peroxide in seawater and the influence on water quality factors. Results showed that the rate of decompound was closely related to their concentration, i.e., the higher concentration and the longer decompound time. In contrast, the rate of decompound of formaldehyde was faster than that of hydrogen peroxide as they were at same concentration. For instance, the completely decompound of 100 mL/m3 formaldehyde need 48 h, while 100 mL/m3 hydrogen peroxide required much more than 96h. However, there were high residues after 7d as they were at 1 500 mL/m3 （for hydrogen peroxide）and 600 mL/m3 (for formaldehyde) into seawater. In addition, the results indicated that there was not significant effect (P>0.05) on temperature, salinity, pH, and dissolved oxygen of seawater as formaldehyde was put into it, however hydrogen peroxide had a significant effect（P
