Description
三フッ化塩素やフッ化水素などの弱酸性ガスを検出するのに適した定電位電解式酸性ガス検出器の電解液は、ヨウ素酸塩としてヨウ素酸リチウムを使用しその濃度を20mmol/L、また臭化物塩として臭化リチウム、ヨウ化物塩としてヨウ化ナトリウムを使用し、これらの合計濃度が500mmol/Lとなるように調整し、その上で電解液中のヨウ化物イオン量を、臭化物イオン量との合計に対する比率、つまりヨウ化物イオン量/(ヨウ化物イオン量+臭化物イオン量)を変化させてオゾンに対する検出感度及び弱酸性ガス応答速度を調査した。
Claims (1)
- 電解液に作用極と対極とを接しさせてなる定電位電解式酸性ガス検出器において、
前記電解液が、ヨウ素酸塩を含む溶液に臭化物塩とヨウ化物塩を、ヨウ化物イオン量/(ヨウ化物イオン量+臭化物イオン量)が、0.1乃至10%となるように混合して調整されている定電位電解式酸性ガス検出器
