| 摘 要： | 向Na2S溶液中通入低浓度SO2气体以生成H2S，H2S从液相中逸出时，存在一突跃现象。本文根据这一现象，结合Y．T．Shah等提出的吸收－反应－解吸体系中过饱和态存在的条件，通过理论分析，得出在Na2S-SO2-H2S4反应体系中H2S解吸存在过饱和现象。

| Abstract: | In the reaction system in which dilute sulfur dioxide is absorped into aqueous sodium sulfide solution and simultaneously hydrogen sulfide is desorped from the solution,the beginning gaseous concentration of hydrogen sulfide desorption from solution increased suddenly.In the light of this phenomenon and the supersaturation condition which is illustrated by Y.T.Shah's et al.for the system of absorption-reaction-desorption,based on the theoretic analysis,this paper came to the conclusion that in the course of hydrogen sulfide desorption there is a supersaturation phenomenon in the reaction system of Na 2S-SO 2 H 2S |
