Description
本発明は、吸着段階、抽出段階、還元段階、発色段階および測定段階、を含んでなっている。各段階を化学的視点からみると、図1のようになる。図1には、窒素酸化物が触媒上に吸着され、これが抽出され、亜硝酸イオンに還元された後発色される一連の過程が示されている。
〔実施例〕
アルミナ「AldI」及び「AldII」〔ともに、アルドリッジ(Aldrich)社製〕、さらにこのアルミナに含浸法によりBa、Ca、Ptを含有させた「20%Ba/AldII」、「1%Pt/AldII」、「1%Pt/5%Ba/AldII、「10%Ca/AldII」、「1%Pt/20%Ba/AldII」および「NaY」を用意して、本発明による定量分析方法により窒素酸化物の量を測定した。
不均一系触媒に吸着された窒素酸化物の量を測定するために、これまで代表的に採用されていた温度調節脱着法(TPD)を利用し、実施例と同じ触媒に対し窒素酸化物の量を測定した。その結果を図5に示した。測定は、TPD方法に熟練した研究員により行われ、一つの触媒に約10時間、8種の触媒で合計80時間要した。
Claims (3)
