The thesis was summarized as follows:<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>The aim of study:<\/strong><\/p>\n<p>synthesize and evaluate of AC\/HKUST-1 composite adsorbent for dye removal by integration activated carbon into HKUST-1 framework, this study aims to enhance its structure properties.<\/p>\n<p><strong>Abstract<\/strong>:<\/p>\n<p>In this study, a hybrid porous composite of activated carbon and HKUST-1 (Cu<sub>3<\/sub>(BTC)<sub>2<\/sub> a type of metal-organic framework.) was fabricated and characterized to enhance the structural framework of a candidate modified adsorbent. This work reports a one pot solvothermal synthesis of an activated carbon \/ HKUST-1 porous composite to provide structural stability and adsorption efficiency in aqueous environments. activated carbon has been integrated into its preparation to improve the adsorption and the structural stability of HKUST-1 results from XRD, SEM, FTIR, BET and EDX revealed an efficient preparation method to create a hybrid structure where well-dispersed HKUST-1 crystals were attached on the activated carbon surface providing a porous structural.<\/p>\n<p>The conditions studied: Percentage of activated carbon in the (0,5,10,15 wt %) Solution\u00a0 pH (2-12), contact time (0.5 to 3.5 hours), adsorbent dose at (0.5to3.5g\/L), initial concentration (20,50,100 ,150, 200,250,and 300 ppm) , agitation speed of an agitation speed=200 rpm, and temperature at 25\u00b0C. The highest removal percentage of methylene blue was 97%\u00a0 accompanied by a maximum adsorption capacity q<sub>max<\/sub> of 282.5 mg\/g . the optimal results were found at pH 7.5,a contact time of 2 hours, an adsorbent dosage of 2 g \/L and an activaited carbon of 10 wt %.<\/p>\n<p>The hybrid composite was evaluated in terms of adsorption performance using methylene blue as a model organic contaminant. The 10 wt% activated carbon\/HKUST-1 composite showed the highest removal rate of 97% which is higher than removal rate of pure HKUST-1 85% while that of pure activated carbon was 66.53%.Furthermore AC\/ HKUST-1 was found to be reusable, with its removal efficiency only dropping by only about 7.67 % after four cycles of use compared to its initial. efficiency.<\/p>\n<p>By hydrothermal synthesis method is a chemical process used ethanol at high temperatures. A solution was prepared by dissolving copper (II) nitrate tri-hydrate (Cu(NO<sub>3<\/sub>)<sub>2<\/sub>3H<sub>2<\/sub>O),trimesic acid (H<sub>3<\/sub>BTC),activated carbon in ethanol, the resulting mixture was mixed at 200 (rpm) at a temperature of 25 \u2103 for 17 minutes ,the suspension was introduced into a Teflon autoclave vessel at 120<sup>o<\/sup> C for 24 h . The powder that resulted from the reaction was filtered and then washed twice with a 60 ml ethanol. It is then dried in a dryer for 5 hours at 60 \u00b0C.<\/p>\n<p>The surface area of the10 wt % of AC loaded was determined to be 541.032 m<sup>2<\/sup>\/g, with the pore volume was measured to be 0.3039 cm<sup>3<\/sup>\/g, which suggested that this sample would be a qualified adsorbent.<\/p>\n<p>Under specific conditions 10 wt % of AC loaded , solution acidity of pH 7.5 , contact time of 2 hours, several MB concentration (20,50,100,150,200,250,and 300 ppm) and isothermal condition justified at 25 \u00b0C, isothermal condition (Langmuir, Freundlich and Temkin models) were investigated to evaluate the use of AC\/HKUST-1 as an adsorbent for removal of methylene blue (MB) from an aqueous solution in isothermal adsorption process.<\/p>\n<p>The results of the adsorption of methylene blue under isothermal conditions best fit to the Freundlich model, as reflected by a high correlation coefficient (R<sup>2<\/sup>) on 0.99.The adsorption kinetics were better described by the pseudo-second model.<\/p>\n<p>This hybrid composite structure shows excellent promise for wastewater treatment and broader environmental remediation .<\/p>\n<p>&nbsp;<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=&#8221;3&#8243; images=&#8221;12323&#8243; img_size=&#8221;large&#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;] \u00a0The Chemical Engineering Department at the College of Engineering, University of Baghdad, held a M.Sc. thesis examination titled: &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.coeng.uobaghdad.edu.iq\/?p=12320\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":165,"featured_media":12322,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[32,31],"tags":[],"class_list":["post-12320","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chemical-engineering","category-thesis"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Examination of M.Sc.
