“…qehes values calculated for Pseudosecond order kinetic are similar with experimental qe values. Pseudo-second order kinetic is the best model for cationic dye removals and this model provided a more accurate and comprehensive reflection of the adsorption mechanism, because of explains the external liquid film diffusion, surface adsorption and intra-particle diffusion processes (Fan, Tang et al, 2016). This result is in agreement with many other studies of kinetics of adsorption of dyes (Özcan, Erdem et al, 2004, Kumar, 2007, El Boujaady, El Rhilassi et al, 2011.…”

ultrasound assisted modification of boron enrichment process waste and using for methylene blue removal from aqueous solutions, Global NEST Journal, 20(X), XX-XX. AbstractIn this study, raw boron enrichment waste was treated with hydrochloric acid and ultrasound at 35-kHz frequency for 60 minutes. To optimize the adsorption conditions for removal of methylene blue (MB) from synthetic wastewaters using raw boron enrichment waste (BEW), acid modified boron enrichment waste (HBEW) and ultrasound modified BEW (UBEW) by adsorption process and to compare the adsorption efficiency of chemical and ultrasonic modifications of BEW were aimed. The optimum adsorption conditions were determined economically and eco-friendly aspect and MB removal percents were found as 80%, 80% and 92% at optimum conditions for BEW, HBEW and UBEW, respectively. The maximum regression coefficient values were obtained as 0.911, 0.998 and 0.984 for BEW, HBEW and UBEW, respectively at Langmuir isotherm model. The adsorption rate was fitted well to pseudo-second order kinetics according to a good correlation coefficient. The adsorption of MB onto adsorbents studied is spontaneous in nature and feasible because of negative ∆G values. The results indicated that the boron enrichment process waste could be a suitable adsorbent for removal of MB from aqueous solution. The maximum adsorption capacities were equal to about 107,0 mg/g, 160,7 mg/g and 145,3 mg/g for BEW, HBEW and UBEW adsorbents at 298 K, respectively. The maximum dye removal percent was achieved for UBEW as 92% and ultrasound assisted modification was found more efficient method compared with acidic modification for MB removal.

In this work, we explore the use of biochar as a remediation agent, and the sensitivity of the spectral‐induced polarization method as a remediation monitoring aid. Biochar amended columns were fully saturated with industrial wastewater (olive oil mill waste) with very high concentration of phenols (∼2485 mg/L) and other substances. The biochar‐amended columns achieved very high removal rates of phenols compared to the control (sand only). Geophysical monitoring over the duration of the experiment (10 days) showed changes in the spectral‐induced polarization signal (imaginary conductivity) consistent with phenol removal as confirmed by geochemical monitoring. This experiment confirmed the utility of biochar as a remediation agent. Furthermore, spectral‐induced polarization can serve as long‐term, high resolution, monitoring aid in organic contaminant degradation processes.

“…The interparticle reaction usually point out the slow step of the adsorption reaction. Pseudo-second-order (Chayid,&Ahmed,2015) TiO 2 / zeolite Amoxicillin -- (Fan et al, 2016) The concentrations of the initial amoxicillin were in the range of 28 to 83 mg L -1 similar with those related in literature in hospital discharge (Kanakaraju;Kockler;Motti, Glass,& Oelgemoller, 2015) (Githinji;Musey;& Ankumah, 2010) (Kavitha,& Namasivayam, 2007). The higher removal percentage was 94% for integrated process with initial amoxicillin concentration of 81.7 mg L -1 resulting in 825.71 mg g -1 higher of those systems found for eucalyptus/ citric acid (Sun, Chen, Wan,& Yu, 2015).…”

Surface water discharge of domestic sewage poses a treat mostly due to antibiotics content as amoxicillin. Its environmental presence provides the bacterial resistance enhancement and disturbance in aquatic life. The biocarbon is an organic carbon compound obtained by biomass pyrolisis at 300 o C to 750 o C under low oxygen environment. It is an effective adsorbent derived from agricultural and industrial solid biomass also frequently used to remove various pollutants, including dyes, pesticides, organic compounds and heavy metals from aqueous solutions. The importance of this natural material rises as low cost abundant and renewable alternative to activated carbon used on wastewater treatment application. Several technologies are employed to modify crude precursors on biocarbon preparation including chemical, physical and biological treatments with the addition of functional groups. The raw biomass material also provides some radicals and humic acids with promising water adsorbent results. The integrated process of the efficient Solar-TiO 2 photodecomposition followed by biocarbon adsorption resulted on 94% of amoxicillin removal percentage and avoids the toxic treatment sludge production.
