Bentonite is used a number of industrial\napplication due to its excellent adsorption and absorption properties. In this research\nwork, activation of bentonite was carried out by using sulphuric acid under different\nconditions of acid concentration, activation time and activation temperature.\nOptimization of activation conditions were conducted by using response surface\nmethodology (RSM). The conditions were 1, 1.5 and 2 M of H2SO4 concentration (x1), 3,\n4 and 5hr activation time (x2), and 90, 100 and 110 ˚C activation temperatures (x3). The\nquality of the second order polynomial model was confirmed the coefficient of\ndetermination, (R2=96.0%). Box-Behnken experimental design indicated that the model\ncan significantly (p < 0.05) express more than 80 % (> 0.80) of the response variation. The\nprepared activated clay was used in the bleaching of sesame oil. The color changes of\nsesame oil before and after bleaching with the prepared activated clay was measured by\nusing Lovibond Tintometer PFXi-195/2 model which can output CIE LAB L*a*b* color\nsystem. Then, the bleaching efficiency of activated clay was determined. The optimum\nactivation condition for maximum bleaching efficiency is 1.5M H2SO4 concentration, 4hr\nactivation time and 100˚C activation temperature and the maximum bleaching efficiency\nis 64.22%.\""}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"\"Bentonite Clay"},{"interim":"Activation"},{"interim":"Bleaching"},{"interim":"Sesame Oil"},{"interim":"Response Surface Methodology\""}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-12-01"}],"displaytype":"preview","filename":"Naw Zar Htwe.pdf","filesize":[{"value":"1018 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/8426/files/Naw Zar Htwe.pdf"},"version_id":"57fe938d-f7ca-40b1-8e2e-2506b26aee9b"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"2022","subitem_journal_title":"Yadanabon University Research Journal","subitem_pages":"337-345","subitem_volume":"Vol.12, No.1"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"\" Naw Zar Htwe\""}]}]},"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":"2022-08-12"},"item_title":"\"Optimization of Activation Conditions on Bentonite Clay for the Bleaching of Sesame Oil Using Response Surface Methodology (RSM)\"","item_type_id":"21","owner":"228","path":["1582966577571"],"publish_date":"2022-12-01","publish_status":"0","recid":"8426","relation_version_is_last":true,"title":["\"Optimization of Activation Conditions on Bentonite Clay for the Bleaching of Sesame Oil Using Response Surface Methodology (RSM)\""],"weko_creator_id":"228","weko_shared_id":-1},"updated":"2022-12-01T06:51:58.763505+00:00"}
