Removal of Disperse Dyes from Water Using Surfactant Treated Alumina

Abstract

An alumina surface was modified by adsorption of an anionic surfactant, sodium dodecyl sulfate (SDS). Typical S-shaped isotherm of surfactant on alumina was observed. The adsorption of Disperse Red-11, Disperse Blue-26 and Disperse Red-156 on alumina and surfactant treated alumina has been investigated. The enhancement in adsorption of these disperse dyes on surfactant treated alumina is observed, which may be attributed to their solubilization in surfactant aggregates formed at the solid/liquid interface. The effect of pH on adsorption has been studied. The adsorption is greatly influenced by pH of the medium. The applicability of the Langmuir model and the Dual-Mode sorption model (DSM) were tested for equilibrium data.

Synthesis of carboxyl‐functionalized magnetic nanoparticles for adsorption of malachite green from water: Kinetics and thermodynamics studies

“…Dyes are used in many industries including textile, leather, food, cosmetics, electronics, paper, rubber, plastic, printing, and pharmaceuticals . Hence, large quantities of dye effluents are generated from these manufacturing processes .…”

Enhancing Remazol Yellow FG Decolorination by Adsorption and Photoelectrocatalytic Degradation

“…The adsorption is one of wastewater treatment that most effective and widely used in the waste treatment process for highefficiency, easy in operation, biodegradability, and low cost (Gupta et al, 2013;Yola et al, 2014) Alumina and silica have high efficiency due to the large of surface area, high porosity, good mechanical properties and good resistivity to thermal degradation (Mahmoud et al, 2010;Malakootian et al, 2015). The surface area of alumina and silica were known 155 m 2 /g and 500 m 2 /g, respectively (Mahmoud, 2005;Gawade et al, 2005). The active surface silica contains silanol (Si-OH) that has an important function in the adsorption process.…”

Efficient adsorbents of nanoporous aluminosilicate monoliths for organic dyes from aqueous solution

“…doi:10.1016/j.jcis.2011.01.006 50), and basic dyes (basic brown 1 and basic violet 3) [7]. Activated alumina is used for dye adsorption as well (crystal violet, malachite green, rhodamine B, methylene blue), but its surface area is small leaded for low-performance removal of dyes [8]. The activated alumina, however, can adsorb cationic dyes easily and obtain the equilibrium state within several minutes.…”
