Experimentally and theoretically approaches for disperse red 60 dye adsorption on novel quaternary nanocomposites

Kinetic mechanism of competitive adsorption of disperse dye and anionic dye on fly ash

The adsorption behavior of four anionic dyes and one disperse dye in single solution and binary solutions on fly ash was investigated in order to elucidate the effect of competitive adsorption on the kinetics. The experimental findings showed that adsorption equilibriums of four anionic dyes were reached within 50 min either in the single solution or in binary mixtures. Competitive adsorption i...

Kinetic Study of Gelatin/Chitosan Based Nanocomposites for Acid Red 150 Dye Adsorption Using Ultrasonic Energy

HE EFFECT of acid red 150 dye (AR150) adsorption parameters onto the prepared gelatin/chitosan/laponite based nanocomposites (NC I, II, III and IV) such as dye concentration, contact time, pH, and sorbent amount using ultrasonic energy had been studied. The standard adsorption affinity through the adsorbent suitability was also carried out. The results revealed that high concentrations of AR150...

Studying the Adsorption Behavior of a Disperse Dye on Polyethylene Terephthalate in Absence and Presence of a Nanostructured Hyperbranched Polymer

Dyeing properties of compounded polyethylene terephthalate fibers with a polyesteramide hyperbranched polymer were investigated in terms of their thermodynamic parameters, including standard affinity -Δμ⁰, enthalpy change ΔH⁰ and entropy change ΔS⁰. Results were then compared with corresponding properties of the virgin PET. The results showed that the isotherms were similar to that of virgin PE...
