According to the lattice parameters. crystal structure of Mn3O4 nanoparticle was found to be tetragonal by XRD. Average crystallite size of the prepared Mn3O4. nanoparticle is 25.60 nm. It was found that the percent crystallinity\r of Mn3O4 nanoparticles was 95.85%. According to Scanning Electron Microscope (SEM) micrograph, Mn3O4 nanoparticles seems tetragonal structure. Application of Mn3O4 nanoparticles was carri ed out for photodecomposition effect. Photodecomposition properties such as effect of contact time and effect of dosage on Mn3O4 nanoparticles were determined in this work. Under the daylight, the decomposition percent of bromocresol green solution was found to be 10.28% and the maximum decomposition percent of this solution increased (48 .78%) for 3 hours under the light of 60 watt electric bulb, the pho todecomposition of bromocresol green solution started after 15 minutes (11.16%) and increased 10 (58.96%) for 3 hours by using 0.3 gm Mn3O4 nanoparticles. The maximum decomposition percent of bromocresol green solution was observed to be 57.85% under the daylight and 67 .92% under the 60 watt electric bulb by using 0.5 dosage. Mn3O4 nanoparticles can be applied for theremoval of dyes in waste water samples. It was observed that colour of the textile dyes solution decreased significantly\r after treatment with Mn3O4 nanoparticles for 2 hours."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Mn3O4 Nanoparticles"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "DMR Journal (ALL).pdf", "filesize": [{"value": "1023 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1023000.0, "url": {"url": "https://meral.edu.mm/record/2723/files/DMR Journal (ALL).pdf"}, "version_id": "1a1594fe-dc74-40e8-a599-0b37ff23d050"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "3, 2015", "subitem_journal_title": "Myanmar Health Sciences Research Journal", "subitem_volume": "27"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Myat Myat Thaw"}, {"subitem_authors_fullname": "Myat Thiyi Kyaw"}, {"subitem_authors_fullname": "Kyaw Naing"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2015"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "http://uyr.uy.edu.mm/handle/123456789/196"}, "item_title": "Removal of Dye in Waste Water by using the Prepared Mn3O4 Nanoparticles", "item_type_id": "21", "owner": "1", "path": ["1582967633684"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002723", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2723", "relation": {}, "relation_version_is_last": true, "title": ["Removal of Dye in Waste Water by using the Prepared Mn3O4 Nanoparticles"], "weko_shared_id": -1}
