Kinetic and modeling data on phenol removal by Iron-modified Scoria Powder (FSP) from aqueous solutions

Abstract

Phenol present in industrial effluents is a toxicant matter which causes pollution of environments aqueous. In this work, scoria was modified by iron in order to increasing of adsorbent efficiency and effective removing of phenol. Effects of independent variables including pH, adsorbents dosage, contact time and adsorbate concentration on removing of phenol were studied by response surface methodology (RSM) based on the central composite designs (CCD). The characterization of raw scoria powder (RSP) and Iron-modified Scoria Powder (FSP) was determined via Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS). The obtained data showed modification by iron caused the growth of new crystalline of iron oxide on the surface of FSP. Evaluated data by RSM indicated the all variables especially pH are effective in removing of phenol (P-value < 0.001) and optimum condition was obtained at pH = 5, phenol concentration = 50 mg/l, adsorbent dosage = 1 g/l and contact time = 100 min to the value of 94.99% with desirability of 0.939. Results revealed that data were fitted by Langmuir isotherm (R2 = 0.9938) and pseudo second order kinetic (R2 = 0.9976). It was found that iron causes increasing the site active of scoria and let to significant removal of phenol.

Dataset on statistical reduction of COD by electrocoagulation process using RSM

“…The maximum 3.8% deviation has been noted for experimental and predicted values of COD (from Equation (1)). The value of 3.97 was noted by a investigator [5]. Percent COD removal = −56.45 + 4.57 × CD + 6.64 × pH + 2.42 × time – 0.097 × CD 2 – 0.299 × pH 2 – 0.02 × time 2 + 0.121 × CD × pH + 10 −3 CD × time – 0.13 pH × time…”

Superior adsorption of methyl blue on magnetic Ni–Mg–Co ferrites: Adsorption electrochemical properties and adsorption characteristics

“…The MB solutions (pH 6.2) were configured with the initial concentrations of 300–3000 mg L −1 , the solutions were adsorbed by the nanoparticles of 5 mg for 2 h and centrifuged at 10,000 rpm for 10 min, then with the distilled water as the reference liquid, the absorbances of the upper clear liquid were measured by the ultraviolet spectrophotometer in 600 nm. Finally, taking the balance concentration of the MB as the horizontal coordinate and the adsorption capacity as the longitudinal coordinate, the experimental data were fitted with different adsorption isotherm 20 models called Langmuir, 21 Freundlich, 22 and Temkin, 23 and the optimal theoretical model was selected based on the correlation coefficient R 2 . In addition, the acid and adsorption capacity of the solution were taken as longitudinal coordinates, and the influence of pH on the reaction was drawn.…”

Dataset for adsorptive removal of tetracycline (TC) from aqueous solution via natural light weight expanded clay aggregate (LECA) and LECA coated with manganese oxide nanoparticles in the presence of H2O2

“…Several kinetics includes pseudo-first-order, pseudo-second-order, intraparticle diffusion of Morris and Weber and elovich (the elovich equation is suitable for systems with heterogeneous adsorbing surfaces) [12] were used to controlling mechanisms of the adsorption process. The equations of kinetic models are expressed as follows [13] , [14] , [15] , [16] :…”
