内容記述 | To estimate precisely an average SO2 concentration in the atmosphere with the lead peroxide method, the actual kinetic expression for SO2-PbO2 reaction system are investigated by regarding the reaction system as a noncatalytic reaction of solid particle with surrounding gas. The reaction models used are progressve-conversion model and unreacted-core model. The experimental research to examine the effect of the atmospheric conditions such as wind velocity, humidity, solute gas concentration, and temperature on the reaction has been performed with the cylindrical PbO2 pellet. The values for the gas film mass transfer coefficient, the effective diffusivity in porous solid, and reaction rate constant are estimated according to the reaction model and experimental data and the rate controlling resistance for the actual kinetic is discussed on the basis of various properties estimated. 二酸化鉛法で求めた大気中の平均亜硫酸ガス濃度を精度良く評価するために, PbO-SO2系反応を固体粒子とそれをとりまくガス間の非触媒反応とみなして, その反応機構を検討した。使用した反応モデルは均一反応モデルと未反応殻モデルである。この反応に及ぼす風速, 湿度, 溶質ガス濃度, 温度などの大気条件の影響を調べるために, 円柱状のPbO2ペレットを用いて実験を行った。ガス境膜物質移動係数, 固体内有効拡散係数および反応速度定数を実験データと反応モデルに基づいて推定した。そして, これらの値を用いてこの反応の速度支配抵抗について検討した。 | |||||
