A STUDY OF HENRY'S LAW CONSTANTS AND DETERMINATION OF VOLATILE ORGANIC CONSTITUENTS IN THE AQUATIC ENVIRONMENT

摘要: 本文给出了简便、可靠的享利常数(Hc)测定方法。研究了温度、离子浓度、悬浮物及分子结构等对Hc的影响,为不同环境水体中有机物挥发速率的研究提供了一定基础。同时,提出了水中有机挥发性物质的三种定量计算方法:三次平衡累积法;多次平衡外推截距法;一次平衡解联立方程法。Abstract: Henry's law constants were determinated by GC multiple phase equilibration method. The method is convenient and accurate. The effect of variables such as temperature, ionic strength, suspended substance and molecular structure on Henry's law constants were studied. The results provide useful information for the study of volatility rate of volatile organic constituents in different aquatic environments. Quantification methods for volatile organic constituents in aquatic environment were suggested.
