HCHO was removed from air using one pass through reactor treatment (5 L\/min). From an initial concentration of HCHO of 0.7 ppm about 96% was removed in one pass treatment using a discharge power of 0.3 W provided by a high voltage amplifier and a Marx Generator with MOSFET switches as pulsed power supplies. Moreover microplasma driven by the Marx Generator did not generate NOx as detected by a chemiluminescence NOx analyzer. In the case of large volume treatment the removal ratio of HCHO (initial concentration: 0.5 ppm) after 60 minutes was 51% at 1.2 kV when using HV amplifier considering also a 41% natural decay ratio of HCHO. The removal ratio was 54% at 1.2 kV when a Marx Generator energized the electrodes with a 44% natural decay ratio after 60 minutes of treatment.<\/jats:p>","DOI":"10.3390\/s121114525","type":"journal-article","created":{"date-parts":[[2012,10,30]],"date-time":"2012-10-30T04:09:59Z","timestamp":1351570199000},"page":"14525-14536","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Study on Decomposition of Indoor Air Contaminants by Pulsed Atmospheric Microplasma"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9914-671X","authenticated-orcid":false,"given":"Kazuo","family":"Shimizu","sequence":"first","affiliation":[{"name":"Organization for Innovation and Social Collaboration, Shizuoka University, 3-5-1 Johoku, Nakaku, Hamamatsu 432-8561, Japan"}]},{"given":"Tomoya","family":"Kuwabara","sequence":"additional","affiliation":[{"name":"Organization for Innovation and Social Collaboration, Shizuoka University, 3-5-1 Johoku, Nakaku, Hamamatsu 432-8561, Japan"}]},{"given":"Marius","family":"Blajan","sequence":"additional","affiliation":[{"name":"Organization for Innovation and Social Collaboration, Shizuoka University, 3-5-1 Johoku, Nakaku, Hamamatsu 432-8561, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2012,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4407","DOI":"10.1016\/S1352-2310(01)00244-8","article-title":"Organic compounds in indoor air\u2014their relevance for perceived indoor air quality?","volume":"35","author":"Wolkoff","year":"2001","journal-title":"Atmos.
