1,189,763. Electro-chemical analysis. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 18, 1968 [Jan. 23, 1967], No. 2894/68. Heading G1N. ,The invention relates to the determination of ozone in the atmosphere (or an oxygen containing gas) by reacting it with an organic compound such as an autoxidizable aldebyde to produce a hydroperoxide, a peroxide, a peracid or a soluble perester. The concentration of the product is estimated from a conductivity measurement. Examples are given using benzoic aldebyde in acetic acid to produce benzoic peracid; heptanal in carbon tetrachloride producing enthanic peracid. The cell comprises a stainless steel block (10) with a hemispherical recess which is platinum or gold plated, and a platinum or gold indicator electrode (8). |
