According to this method a certain amount of gas is bubbled through the neutral (pH = 7) 2% KI solution. After that the pH is adjusted to 2 by addition of H2SO4. Eliberated iodine is titrated back with Na2S2O3 solution to a starch endpoint. Contemporary ozone analyzers for gas are operating on the principle of UV-light absorption at the wavelength of 254 nm. Dissolved ozone can also be measured according to the same principle at the wavelengths of 253.7 or 258-260 nm.<\/p>\n<p>To determine the concentration of dissolved ozone besides 0.2% solution of KI also the indigo trisulfonate solution can be used (Hoigne &amp; Bader, 1979-1982). The disappearance of its blue color can be monitored spectrophotometrically at 600 nm.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-181 size-full\" src=\"https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/8.jpeg\" alt=\"\" width=\"200\" height=\"153\" \/><\/p>\n<p><strong><em>ATI ozone analyzer in gas<\/em><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-183 size-medium\" src=\"https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/9-300x225.jpeg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/9-300x225.jpeg 300w, https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/9-768x576.jpeg 768w, https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/9-705x529.jpeg 705w, https:\/\/loiteh.ee\/wp-content\/uploads\/2024\/06\/9.jpeg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p><strong><em>ATI dissolved ozone analyzer in water<\/em><\/strong><\/p>\n<\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":324,"menu_order":3,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-335","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/pages\/335","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/comments?post=335"}],"version-history":[{"count":3,"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/pages\/335\/revisions"}],"predecessor-version":[{"id":338,"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/pages\/335\/revisions\/338"}],"up":[{"embeddable":true,"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/pages\/324"}],"wp:attachment":[{"href":"https:\/\/loiteh.ee\/en\/wp-json\/wp\/v2\/media?parent=335"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
