ABSTRACT The present study focused onto adsorptive properties and nature of the interaction between sodiumcarboxymethylcellulose (NaCMC) and mesoporous granular fine quartz (MGFQ) applying various in-depth characterization techniques, adoption isotherm models including statistical aspects and operation variables. The physiochemical parameters of MGFQ such as specific surface area (SBET )=11.34 m2/g, pore volume (Vp)=0.09 cm3/g, total pore volume (Vtp)=0.09 cm3/g, mean pore diameter=32.52nm were determined. The thermal result revealed that NaCMC could be used at moderate temperature (251°C), which was suitable for its application. The equilibrium isotherm data were fitted with Langmuir, Freundlich, Temkin and Jovanovic model of adsorption and compered by linear determination coefficient (R2), obeyed the order as Freundlich (R2=0.9984)> Langmuir (R2=0.9194)>Temkin (R2=0.8899)>Jovanovic (R2=0.8709). The infra-red spectral changes in the region 1104cm−1 and 1076cm−1 suggested that NaCMC accumulation onto MGFQ was stabilized by H-bonding and some other weak noncovalent interactions depending on the solution optimized conditions.
