为模拟化学品泄漏后水中漂移扩散情况,通常使用数值模型,如Chemmap。Chemmap模型的设计仍存在多项不足之处。本研究通过实验测定苯、苯乙烯、萘、三氯乙烯四种单体以及苯和苯乙烯混合物在长江重庆段水样中大气-水分配平衡常数,建立了实验方法体系。结果发现,实验测定结果与理论值存在较大差异,建议在无法获得分配平衡系数或数据不可靠或理论估算值存在偏差的情况下,采用实际水样的实验方法获得相应系数。
Experimental Study on Air-water Two-phase Distribution Equilibrium of Water Samples in Chongqing Section of Yangtze River
This study established an experimental method system by measuring the atmospheric-aqueous distribution equilibrium constants of four monomers, benzene, styrene, naphthalene, and trichloroethylene, as well as a mixture of benzene and styrene, in water samples from the Chongqing section of the Yangtze River. It was found that there was a significant difference between the experimental measurement results and the theoretical values. It was recommended to use the experimental method of actual water samples to obtain the corresponding coefficients in cases where the distribution equilibrium coefficient could not be obtained, the data was unreliable, or there was a deviation in the theoretical estimation value.
