Synthesis and Evaluation of MgO-Supported Activated Carbon for Carbon dioxide Capture
Abstract: Carbon dioxide (CO₂) capture has emerged as a critical strategy for mitigating greenhouse gas emissions and addressing global climate change. In this study, a series of MgO-supported activated carbon adsorbents containing 2, 4, 6, 8, and 10 wt% MgO were successfully synthesized using the impregnation method to evaluate their CO₂ adsorption performance. The structural, chemical, and surface properties of the prepared materials were characterized using powder X-ray diffraction (PXRD), Fourier-transform …

Continuous Column Study of Chromium (VI) Adsorption by Ion Exchange Resin
Abstract: The Indion GS300 anion exchange resin was trialed for its ability to remove chromium (VI) from synthetic wastewater by continuous column experiments. The ability of Indion GS300 to adsorb chromium (VI) in a fixed-bed column was analyzed. The effects of operating parameters such as flow rate and bed depth on the sorption characteristics of Indion GS300 were investigated. The total adsorbed quantities, equilibrium characteristics were related to the effluent volumes …

Pressure Swing Adsorption Process for Reduction of Argon-41 Release from Nuclear Reactor Exhaust Systems
Abstract: In several nuclear reactors, huge quantity of air (in the order of 10,000 cmh) is continuously passed to cool the calandria vault. This results in high radiation field due to argon-41. It is necessary to isolate and recover argon from these environments, which can bring down the activity release to the atmosphere in attaining ALARA principle. Pressure swing adsorption (PSA) technique has been employed by combining molecular sieves 5A (MS5A) …

Clay–Polymer Nanocomposites: An Efficient Adsorbent for Waste Water Treatment
Abstract: Despite the abundance of water sources, the globe today lacks potable water because to pollution. Pollutants can be removed from water using a variety of technologies, but adsorption is considered the most simple, effective, economical, and ecologically beneficial method. The class of adsorbents known as clay–polymer nanocomposite (CPN) adsorbents is one that is now gaining popularity. By adsorbing and flocculating inorganic and organic micropollutants from water, CPNs efficiently cleanse water. …

Pressure Swing Adsorption Technique for Separation and Containment of Argon-41
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 Air is used as a coolant in several nuclear facilities especially in the Pressurized Heavy Water Reactors (PHWRs). When air interacts with the neutron field, the Argon-40 present (0.93%) in the air gets neutron-activated to form Argon-41which is a beta and gamma emitter, with a half-life period of 1.83 h. Argon-41 is a major radioactive effluent in nuclear reactors accounting for a larger percentage …
