Chitosan resins, which clinically served as adsorbents in hemoperfusion therapy, were prepared with reversed-phase suspension methodology using three differently structured crosslinking agents, methanal, glyoxal and glutaraldehyde. And the glyoxal and glutaraldehyde crosslinked chitosan resins were reduced with NaBH4 afterwards. By analyzing the results from FTIR and SEM, it was found that the ...

Tissue particles from a wide variety of animal tissues possess the capacity to combine with PVM. Various adsorbents also combine with the virus. Elution of PVM from combination with either tissue particles or adsorbents can be achieved by appropriately altering the ionic environment. Influenza viruses also are adsorbed on and eluted from adsorbents under similar conditions. Reasons are presente...

Background and Objectives : Ethylbenzene (EB) is a dangerously organic compound which the presence of this pollutant in water solutions can be considered as an environmental and public health hazard. In this study, nano magnetic particles (Fe 3 O 4 ) were used as an adsorbent to remove ethylbenzene from aqueous solutions. Methods : The specification of the adsorbent was investigated by transmis...

Abstract The growing global economy resulted in an incessant increase transportation and exploitation of oil. Hence, the oil spillage has been considered a serious threat to aquatic terrestrial ecosystems. Therefore, water purification major challenge around world. There are numerous classical methods available for removal from water, but owing multiple defects disadvantages, research efforts h...

Silica monolith aerogels with different degrees of hydrophobicity by incorporating methyltrimethoxysilane (MTMS) or trimethylethoxysilane (TMES) in standard sol-gel synthesis were prepared. Excellent properties of the aerogels, obtained with the sol-gel synthesis, were preserved with supercritical drying with CO2. The degree of the hydrophobicity of the aerogels was tested by measuring the cont...

Nano-materials and thin films have immense potential in supporting various applications such as purifying water resources, treating water-borne diseases, detecting pollutants through sensors, most importantly, preventing contamination. However, providing contamination-free for healthy living remains a challenging issue, many parts of the world are facing severe scarcity pollution problems. This...

In order to study the influences of functionalized groups onto the adsorption of tetracycline, we prepared a series of amino and amino-Fe3+ complex mesoporous silica adsorbents with diverse content of amino and Fe3+ groups (named N,N-SBA15 and Fe-N,N-SBA15). The resulting mesoporous silica adsorbents were fully characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectrom...

In this article, the technical feasibility of various low-cost adsorbents for heavy metal removal from contaminated water has been reviewed. Instead of using commercial activated carbon, researchers have worked on inexpensive materials, such as chitosan, zeolites, and other adsorbents, which have high adsorption capacity and are locally available. The results of their removal performance are co...

Recent efforts have been directed towards the design of efficient and contaminant selective remediation technology for the removal of perfluorinated compounds (PFCs) from soils, sediments, and aquatic environments. While there is a general consensus on adsorption-based processes as the most suitable methodology for the removal of PFCs from aquatic environments, challenges exist regarding the op...
