Adsorptive removal of anionic dye by inorganic–organic hybrid anion-exchange membranes

Removal of transition metal ions from aqueous solutions by adsorption using a novel hybrid material silica gel chemically modified by triethylenetetraminomethylenephosphonic acid

“…S1 (1). The peak at 972 cm −1 is a characteristic peak for the stretching vibration of P-O in the -PO 3 2− ions. The results of FT-IR analysis further demonstrated that the adsorption of GH-T-P for Au(III) were carried out through chemical adsorption mechanism, which means N and O atoms of the functional groups of adsorbent GH-T-P seemed to complex with Au(III).…”

“…On the other side, inorganic-organic hybrids offer very interesting actual and potential applications, and may have prominent properties in areas such as adsorbents [3]. Due to the excellent thermal and mechanical stability, unique large surface area and well-modified surface properties, silica gel was widely used as inorganic solid matrix in inorganic-organic composite materials.…”

Adsorption kinetic, equilibrium and thermodynamic studies of Eosin-B onto anion exchange membrane

“…Cationic dye methyl violet 2B was removed from aqueous solution by two kinds of membranes P81 and ICE450 via adsorption process [26]. Similarly, AEMs was developed for adsorption removal of anionic dye Cibacron Blue 3GA from aqueous solution [27]. In our previous research, we have employed AEMs for removal of different dyes from water via adsorption process [28][29][30][31].…”

Adsorption of Textile Dye on Zinc Stannate Oxide: Equilibrium, Kinetic and Thermodynamics Studies

“…Adsorption techniques water treatment has received much attention in recent years since conventional treatment methods have shown limitations to recover dyestuffs from water due its chemical and biological stability (3). Adsorbents materials that have been proposed including carbon (4), clays (5) chitosan (6), vegetable fibers (7), waste materials (8)(9)(10)(11)(12), bamboo (13), zeolite (14)(15)(16), ion-exchange membrane (17,18), composite (19,20), polymer (21), and oxides (22)(23)(24). Zn 2 SnO 4 ternary oxide is known to have high electrical conductivity, high electron mobility, and low visible absorption (25), which makes it suitable for a wide range of applications, such as gas-sensing material (26), anode material for Li-ion batteries (27), photocatalyst for degradation of benzene (28), and organic dye (29).…”
