Box-Behnken design was employed for optimization of UV/TiO2process. Four independent variables namely initial dye concentration, pH, photocatalyst dosage and UV irradiation time was chosen as processvariables. According to ANOVA, it was observed thatthe initial dye concentrationand pH was statistically the most significant for decolourization efficiency response, with confidence level of 99.99%, followed by the UV irradiation time (97.54%). It has also been observed that the highest interaction (99.81%) occurred between the initial dye concentrationand pH.Optimization resultshowed that maximum decolourization of dye solution (96%) was achieved at the optimum conditions: initial dye concentration 50 mg/L, pH 3, photocatalyst dosage 1 g/L and irradiation time 180 min. Predicted values of decolourization efficiency were found to be in good agreement with experimental values (R2= 0.9557and Adj-R2= 0.9323).These results indicatethat the optimization based on the Box-Behnkendesign can effort by the estimation of the optimum conditions for the maximum decolourization efficiency."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "decolourization"}, {"interim": "dye solution"}, {"interim": "catalyst"}, {"interim": "uv irradiatio"}, {"interim": "response surface methodology"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_no", "date": [{"dateType": "Available", "dateValue": "2020-09-10"}], "displaytype": "preview", "filename": "SSH.pdf", "filesize": [{"value": "529 Kb"}], "format": "application/pdf", "licensetype": "license_0", "url": {"url": "https://meral.edu.mm/record/5330/files/SSH.pdf"}, "version_id": "7d5cfef0-6a12-4c24-a903-7ca468cc8ac7"}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_c_date": "2017-11-06", "subitem_conference_title": "10th Regional Conference on Chemical Engineering (Sustaining Chemical Engineering Ingenuity and Breakthroughs Towards a Successful ASEAN Integration)", "subitem_place": "Hotel Benilde Maison de la Salle, Manila, Philippines"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Su Su Hlaing"}, {"subitem_authors_fullname": "Lat Lat Tun"}, {"subitem_authors_fullname": "Tint Tint Kywe"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_name_i18n": "Upload type", "attribute_value": "Publication"}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_name_i18n": "Publication type", "attribute_value": "Conference paper"}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_name_i18n": "Publication date", "attribute_value": "2017-11-06"}, "item_title": "Optimization of Photocatalytic decolourization of Red Dye in an Aqueous Suspension of Titanium Dioxide Using Response Surface Methodology", "item_type_id": "21", "owner": "30", "path": ["1582963413512/1596105561292"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000005330", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-09-10"}, "publish_date": "2020-09-10", "publish_status": "0", "recid": "5330", "relation": {}, "relation_version_is_last": true, "title": ["Optimization of Photocatalytic decolourization of Red Dye in an Aqueous Suspension of Titanium Dioxide Using Response Surface Methodology"], "weko_shared_id": -1}
