The PEC process employing a Gr\/Ni-Sb-SnO\u2082 photo-anode resulted in 83.7% tetracycline removal with relatively low energy consumption, while exhibiting a clear synergistic effect compared to photocatalysis alone. Furthermore, the developed Gr\/Bi-Ni-Sb-SnO\u2082 photo-anode demonstrated high photocatalytic activity and excellent stability over multiple operational cycles. In treating petroleum refinery wastewater, a COD removal efficiency of 86.2% was achieved, following pseudo-first-order kinetics.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: Arial; font-size: 17px;\">\u00a0The outcomes of this work were published in internationally indexed journals ranked within Q1 and Q3, as well as in peer-reviewed local journals, and were submitted for Iraqi patents, highlighting the scientific significance and practical applicability of the proposed photo-anode system.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: Arial; font-size: 17px;\">\u00a0Based on these findings, future work is recommended to expand the application of the system to other persistent pollutants, evaluate its performance under natural solar irradiation, assess long-term electrode stability, and investigate scale-up and integration with advanced oxidation or biological treatment processes.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6620&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6621&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6616&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6615&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6619&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6618&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] \u00a0On Thursday, February 2nd, 2026 at the college thesis hall, Al-Khwarizmi College of Engineering &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.kecbu.uobaghdad.edu.iq\/?p=6613\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":27,"featured_media":6619,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"no","_lmt_disable":"","footnotes":""},"categories":[3,8],"tags":[],"class_list":["post-6613","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 -
