The elemental compositions of clam shells powder were determined by Energy Dispersive X-Ray Fluorescence (EDXRF) method. In this research work, calcium chloride, calcium sulphate dihydrate (gypsum) and calcium sulphate hemihydrates (plaster of paris) were prepared from clam shells powder. Determination of the optimum conditions for the conversion of clam shell to calcium chloride, calcium sulphate dihydrate and calcium sulphate hemihydrate were conducted using different parameters such as various amount of acids, reaction times and temperatures and also various salting-out agents. The compounds and elemental compositions of prepared calcium chloride, calcium sulphate dihydrate and calcium sulphate hemihydrates were determined and compared with that of the commercial products."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Clam shells"}]}, "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": "Utilization of Calcium Carbonate (Clam Shell)pdf.pdf", "filesize": [{"value": "526 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 526000.0, "url": {"url": "https://meral.edu.mm/record/690/files/Utilization of Calcium Carbonate (Clam Shell)pdf.pdf"}, "version_id": "e5466bc0-1291-4161-9740-b55d49651b8d"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Universities Research Journal", "subitem_volume": "6"}]}, "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": "Aye Aye Mar"}, {"subitem_authors_fullname": "Hsu Mon Phyo"}]}]}, "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": "2013"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://umoar.mu.edu.mm/handle/123456789/216"}, "item_title": "Utilization of Calcium Carbonate (Clam Shell)", "item_type_id": "21", "owner": "1", "path": ["1582967133536"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000690", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "690", "relation": {}, "relation_version_is_last": true, "title": ["Utilization of Calcium Carbonate (Clam Shell)"], "weko_shared_id": -1}
