Het systeem levert nauwkeurige COD\u2011resultaten in ongeveer 10 minuten, zonder gebruik te maken van gevaarlijke chemicali\u00ebn zoals dichromaat of kwik.<\/p>\n<p data-start=\"490\" data-end=\"754\">De technologie is gebaseerd op een gepatenteerde nanotechnologie en is geschikt voor toepassingen in zowel afvalwater als drinkwater. PeCOD verhoogt de analysesnelheid en verlaagt tegelijk de milieubelasting en gezondheidsrisico\u2019s in laboratorium\u2011 en operationele omgevingen.<\/p>\n<\/div>\n<h3 data-section-id=\"1w626sa\" data-start=\"761\" data-end=\"800\"><strong>Veilige en duurzame chemie\u00a0<\/strong><\/h3>\n<p data-start=\"802\" data-end=\"956\">De kern van het systeem is de PeCOD\u2011sensor, die gebruikmaakt van een met UV\u2011licht geactiveerde titaniumdioxide\u2011 (TiO\u2082) nanodeeltjes\u2011fotokatalysator, gekoppeld aan een extern circuit.<\/p>\n<p data-start=\"958\" data-end=\"993\"><strong>Wanneer een monster de microcel binnenkomt:<\/strong><\/p>\n<ul data-start=\"995\" data-end=\"1178\">\n<li data-section-id=\"1hlyiv7\" data-start=\"995\" data-end=\"1042\">wordt de TiO\u2082\u2011sensor belicht met UV\u2011licht,<\/li>\n<li data-section-id=\"ctdwin\" data-start=\"1043\" data-end=\"1074\">wordt een potentiaalbias toegepast,<\/li>\n<li data-section-id=\"gxmpsq\" data-start=\"1075\" data-end=\"1129\">ontstaan fotogaten met een zeer sterk oxidatievermogen,<\/li>\n<li data-section-id=\"slnmyr\" data-start=\"1130\" data-end=\"1178\">worden organische verbindingen in het monster geoxideerd.<\/li>\n<\/ul>\n<p data-start=\"1180\" data-end=\"1428\">Dit proces maakt een vrijwel volledige oxidatie van organische stoffen mogelijk en levert een betrouwbare COD\u2011waarde voor een breed scala aan verbindingen. Dankzij het sterke oxidatievermogen van door UV belicht TiO\u2082 is de oxidatie consistent en reproduceerbaar.<\/p>\n<h3 data-section-id=\"g21fl0\" data-start=\"1435\" data-end=\"1481\"><strong>Waarom wordt PeCOD beschouwd als een veiligere COD-methode?<\/strong><\/h3>\n<p data-start=\"1483\" data-end=\"1629\">PeCOD volgt het principe van green chemistry en vormt een veilig alternatief voor traditionele COD\u2011methoden. Het systeem heeft geen gevaarlijke reagentia zoals dichromaat of kwik nodig.<\/p>\n<p data-start=\"1631\" data-end=\"1652\"><strong>De belangrijkste voordelen zijn:<\/strong><\/p>\n<ul data-start=\"1654\" data-end=\"1842\">\n<li data-section-id=\"1h414vo\" data-start=\"1654\" data-end=\"1693\">Geen gebruik van toxische oxiderende chemicali\u00ebn<\/li>\n<li data-section-id=\"1dm5tc2\" data-start=\"1694\" data-end=\"1747\">Lagere risico\u2019s voor laboratoriummedewerkers en operatoren<\/li>\n<li data-section-id=\"1umeod2\" data-start=\"1748\" data-end=\"1796\">Veiligere hantering in alle fasen van de analyse<\/li>\n<li data-section-id=\"1ntlnvh\" data-start=\"1797\" data-end=\"1842\">Milieuvriendelijkere analytische workflow<\/li>\n<\/ul>\n<p data-start=\"1844\" data-end=\"1931\">Dit maakt het systeem veilig voor zowel laboratorium\u2011 als operationeel personeel.<\/p>\n<h3 data-section-id=\"1gufa3v\" data-start=\"1938\" data-end=\"1992\"><strong>Hoe snel en nauwkeurig is COD\u2011meting met PeCOD?<\/strong><\/h3>\n<p data-start=\"1994\" data-end=\"2214\">PeCOD is ontwikkeld voor snelle COD\u2011bepaling en levert <strong>resultaten in ongeveer 10 minuten<\/strong>. Dit ondersteunt snelle besluitvorming bij procescontrole en milieumonitoring.<\/p>\n<p data-start=\"2216\" data-end=\"2305\">De technologie biedt hoge nauwkeurigheid over een breed spectrum aan organische verbindingen.<\/p>\n<h3 data-section-id=\"1e5lauf\" data-start=\"2312\" data-end=\"2372\"><strong>Relatie tot BOD en traditionele COD\u2011methoden<\/strong><\/h3>\n<p data-start=\"2374\"
