Removal of aqueous organic pollutants by adsorption-catalytic process using mesoporous carbon beads loaded with metal oxides

The use of superporous p(3-acrylamidopropyl)trimethyl ammonium chloride cryogels for removal of toxic arsenate anions

“…Due to their structural flexibility, higher mechanical strength and fast responsiveness, cryogels provide many advantages in comparison to conventional hydrogels (Gulsu et al, 2010;Lozinsky, 2008;Sahiner and Seven, 2014a;. The applications of cryogels include template for metal nanoparticles (Sahiner and Seven, 2014b;, bioreactor (Wang et al, 2013), column (Wang et al, 2014;Yao et al, 2006) cell-scaffolds (Hwang et al, 2010), biosensor (Hedstr€ om et al, 2008;Tsai et al, 2007), and absorbents for environmental applications (Koc et al, 2011;Yamamoto et al, 2009Yamamoto et al, , 2010. Earlier the removal of arsenic with p(APTMACl) and bulk hydrogels was reported (Barakat and Sahiner, 2008;Sahiner et al, 2011).…”

Catalytic ozonation of aqueous phenol over metal-loaded HZSM-5

“…Adsorption of phenol on zeolite generates the concentrated zones whilst metal oxides decompose dissolved ozone in order to enhance the rate of ozonation reaction (Yamamoto et al 2009). Moreover, the removal of phenol from adsorbed surface can regenerate zeolite automatically since impregnation of metals oxides on zeolite may enhance ozonation of phenol.…”

Catalytic ozonation process using a MgO nano-catalyst to degrade methotrexate from aqueous solutions and cytotoxicity studies in human lung epithelial cells (A549) after treatment

“…MgO, due to its adsorption properties, is also a promising substance as an adsorbent. 29 MgO is a material with a wide application range. 24 MgO is heterogeneous which means it has high catalytic potential for the degradation of refractory pollutants, such as drugs.…”
