摘要
介绍了一次、二次及多次相平衡/液上色谱法测定水中有机挥发烃及其气液分配常数的理论关系式。给出分配常数倒数与定量分析误差存在线性关系;研究了温度、离子强度等因素对分配常数的影响。
The procedure for determination of volatile hydrocarbons concentrations in water and their partition constants using multiple equilibrium/he-adspace GC was investigated. The measured error increased linearly with r/KD. The effects of temperature, ionic strength, gas/liquid ratio on measured partition constants were discussed.
