Adsorption of turquoise blue QG reactive bye commercial activated carbon in batch reactor: kinetic and equilibrium studies

Abstract: -The adsorption of reactive turquoise blue QG dye on commercial activated carbon was investigated in a batch reactor to obtain isotherm and kinetic data under different experimental conditions. The adsorbent was characterized by a FTIR method to analyze surface area and pH PZC and to identify functional groups. Experiments were conducted to obtain equilibrium data at 30°C, with the pH effect being assayed in the range of 2 to 8. Experiments were then carried out under the optimal pH condition for dye removal t… Show more

“…The functional groups of the S. platensis biomass were identified using infra-red analysis (FT-IR) (Prestige 21, the 210045, Japan) (Mona et al, 2011). The specific surface area, pore volume and average pore radius were determined by standard BET N 2 -adsorption methods (Quantachrome, Nova station A, USA) (Schimmel et al, 2010). Scanning electron microscopy (SEM) was used to verify the surface characteristics of the S. platensis particles (Jeol, JSM-6060, Japan) (Bangash and Alan, 2009).…”

“…The values of zero point charge (pH zpc ), specific surface area, pore volume and average pore radius of the biosorbent are very important to understand the biosorption mechanisms (Schimmel et al, 2010). The zero point charge (pHzpc) of the S. platensis biomass (obtained by the eleven point's experiment) was 7,…”

“…Also, dyes can be effectively removed by an adsorption process in which dissolved dye compounds attach themselves to the surface of adsorbents. Various adsorbents such as: activated carbon (Khaled et al, 2009;Bangash and Alam, 2009;Schimmel et al, 2010), flay ash (Lin et al, 2008), sawdust (Bello et al, 2010), lignite (Pentari et al, 2009), bentonite (Bulut et al, 2008), sepiolite (Dogan et al, 2007), montmorillonite , polymers (Kim and Guiochon, 2005), resin (Coşkun, 2011), zeolite (Mesko et al, 2001), macroporous hydrogel (Li et al, 2010), orange peel (Mafra et al, 2013), chitosan (Piccin et al, 2011), etc. have been widely studied for dye removal from aqueous solution.…”

“…They observed the monolayer adsorption capacities of 11.63 mg/g and 6.22 mg/g for Reactive red 120 dye and Reactive black 5 dye, respectively. Schimmel et al (2010) studied the adsorption potential of commercial activated carbon for Turquoise blue QG reactive bye. The adsorption studies were conducted to obtain isotherm and kinetic data under different experimental conditions.…”
