Adsorption of Reactive Blue 114 dye by using a new adsorbent: Pomelo peel

Agricultural waste peels as versatile biomass for water purification – A review

“…The removal of Reactive Blue 114 dye from aqueous solutions was also studied by using pomelo peels [48]. The surface area and average pore radius were 0.034 m 2 /g and 1.3 × 10 −3 µm, respectively, as measured using the BET (Brauner Emmett Teller) method with nitrogen gas.…”

Agricultural peels for dye adsorption: A review of recent literature

“…2) was used as materials for the removal of RB114 [68]. The pH-effect experiments were carried out in the range 2-11; based on those results, increasing the solution pH, the zeta potential values increased (approximately from − 3 mV to − 30 mV) and as a result the negative charged dye molecule could not be adsorbed to the negative charged surface (repulsive forces).…”

Equilibrium, Kinetics and Thermodynamics Studies on the Bisorption of Textile Dyes onto Polyamidoamine Dendrimer Functionalized Soy Hull

“…The phenomena can be explained that the higher initial concentration of organic dyes provides a stronger driving force to overcome the mass transfer resistance of all molecules between the aqueous and solid phases. In addition, according to the adsorption mechanism, the organic dye molecules were adsorbed on external surface firstly, and then diffused into the porous structure of the adsorbent [6]. Similarly, the adsorption capacity of crystal violet from aqueous phase on Formosa papaya seed powder (FPSP) increased with an increase in the dye's initial concentration suggesting that available sites on the adsorbent are the limiting factor for dye adsorption [7].…”
