After the candidate had finished the defense, the chair of the committee announced the degree of excellence awarded to the candidate for her research findings which are summarized:<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">\u00a0 This study investigates the elimination of antibiotic tetracycline (TC) utilizing a green photocatalytic copper oxide\/zinc oxide nanocomposite synthesized through the liquid-phase reduction process. It employs eucalyptus leaf extract as both a reducing and capping agent (CuO\/ZnO\u2014NCs). Different molar ratios of Cu to Zn salts (1:3, 1:6, 1:9, and 1:12) were used.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">Characterization techniques were applied to the produced nanocomposite such as Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDAX), X-Ray Diffraction (XRD), Fourier- Transformed Infrared Radiation (FT-IR), Brunauer- Emmet- Teller (BET), and zeta potential. The study examined the effect of the most significant variables such as pH, (CuO\/ZnO) NCs dosage and the catalyst height, initial TC concentration, H<sub>2<\/sub>O<sub>2<\/sub> dosage, UV intensity, flow rate, and temperature on the photocatalytic process using a batch and continuous mode. In addition, the kinetic study and thermodynamic parameters for photocatalytic reactions such as \u2206\ud835\udc3a\u00b0, \u2206\ud835\udc3b\u00b0, and \u2206\ud835\udc46\u00b0 were studied.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image source=&#8221;external_link&#8221; css=&#8221;&#8221; custom_src=&#8221;https:\/\/kecbu.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/29\/2025\/02\/474761488_1087632363398613_8724651591309267850_n.jpg&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image source=&#8221;external_link&#8221; css=&#8221;&#8221; custom_src=&#8221;https:\/\/kecbu.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/29\/2025\/02\/475291867_1087632330065283_3783677371333601664_n-1.jpg&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image source=&#8221;external_link&#8221; css=&#8221;&#8221; custom_src=&#8221;https:\/\/kecbu.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/29\/2025\/02\/474762336_1087632273398622_2719934015927499005_n.jpg&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image source=&#8221;external_link&#8221; css=&#8221;&#8221; custom_src=&#8221;https:\/\/kecbu.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/29\/2025\/02\/475138476_1087631656732017_549754002032407006_n.jpg&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] The master thesis of the graduate Marwa Saad Abdel Ameer, a candidate for a master&#8217;s &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.kecbu.uobaghdad.edu.iq\/?p=5562\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":27,"featured_media":5563,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[3,8],"tags":[],"class_list":["post-5562","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-latest-news","category-masters-discussions"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
