“…Literatures reported that maximum phenol removal by soil occurred at solution pH 6.0. [36]- [38]. The study revealed that the increased removal percentage with increase of initial phenol concentrations from 0.5 to 4 mg/L, accomplishing the maximum removal (95.30 %) at an initial concentration of 4 mg/L and then found to be decreased marginally beyond it towards the initial phenol concentration of 10 mg/L.…”

Abstract-Use of compacted silty clay soil collected from the Gangetic river sediment near Kolkata, West Bengal, India has been experimentally explored in the laboratory as a low cost landfill liner material for retarding the migration of phenolic compounds releasing from a coke oven wastewater outfall site in Durgapur, West Bengal, India. The phenol concentration in the wastewater was found in the range of 4.0-12.0 mg/L in different times of a calendar year. Batch adsorption results reveal that the maximum phenol removal efficiency of 95% was achieved at an initial phenol concentration of 4 mg/L for the soil dose of 20 g/L, solution pH of 6.0 and after a reaction time of 24 h. Index properties, swelling potential, compaction characteristics and permeability of the soil indicate that it is low compressible, moderately expansive and low permeable (1.90×10 -8 cm/s) and having reasonably good phenol attenuation capacity (472.5 mg/g). These favorable findings suggest that the compacted clay soil can be potentially utilized as primary landfill liner material for containment of phenolic waste generated from coke oven wastewater.

In the present study, optimization of phenol adsorption onto garlic peel (GP) was conducted with process parameters such as initial pH, adsorbent dosage, agitation speed, and contact time. The percentage removal of phenol was optimized based on these process parameters. Response surface methodology was used for optimization as it has many advantages over classical optimization methods. A Box-Behnken experimental design was employed. The optimum conditions for maximum removal of phenol from an aqueous solution of 50 mg L −1 were found as follows: pH: 2, adsorbent dosage: 2.1 g L −1 , contact time: 7 h, and agitation speed: 135 rpm. At these optimized conditions, batch adsorption experiments were conducted to study the effects of initial concentration and temperature on phenol removal. Thermodynamic parameters such as DG ; DH and DS were also evaluated. From the results, the sorption process was found to be spontaneous and exothermic. The equilibrium experimental data were analyzed with several isotherm models. The adsorption kinetics for phenol removal by GP follows the pseudo-second-order kinetic model. The results from the study demonstrated that more than 80% phenol removal is possible at the above-mentioned optimum conditions.
