“…The nature of the surface of the pine cone powder also affects the overall biosorption mechanism. Earlier, similar behavior was also observed the adsorption of chlophenols on other adsorbents, such as Acacia leucocephala bark [18], pine bark powder [20], activated carbon produced using palm empty fruit bunch, coconut husk, activated clay, coconut shell [37][38][39][40], and various agricultural wastes, e.g., sunflower seed hulls, pumpkin seed shells, walnut shells and peanut shells [21]. Therefore, all the remaining experiments were conducted at the optimum pH value of 6. owing to enhanced active sites on the surface of the adsorbent, making TCP penetration easier into the active sites [20].…”

“…Several studies proved biosorption is a simple yet effective method for the elimination of pollutants, in which the significant factor is the utilization of agricultural wastes. Many authors highlighted the fact that the biosorption of phenol and phenolic derivatives using lignocellulosic residues and agricultural by-products do not require recycling and regeneration studies due to their low-cost and abundant availability in nature [2,[18][19][20][21].Pine trees annually produce large amounts of pine cones as an agricultural waste. Each cone consists of an axis, which is composed of several woody scales arranged in a spiral fashion.…”

The present work discusses the adsorptive removal of a phenolic pollutant, i.e., 2,4,6-trichlorophenol (TCP), using low cost untreated agricultural waste pine cone powder (PCP). The present biosorbent was thoroughly characterized with the help of FTIR, SEM, XRD, and CHN analysis. The presence of amine (-NH 2 ), hydroxyl (-OH) and carbonyl (C=O) functional groups was detected by the FTIR analysis. The important biosorption factors like agitation time, biomass dosage, initial adsorbate concentration, and the initial pH were examined by batch studies. The biosorption kinetic process was fast, reaching equilibrium in 75 min. The experimental kinetic data revealed an excellent agreement with the pseudo second order (PSO) model. On the other hand, the Langmuir isotherm model best described the equilibrium data with the maximum biosorption capacity (q max ) of 243.90 mg/g. These values are better than the adsorption capacities of most agro-based untreated adsorbents previously reported in the literature. Owing to fast removal rates and high biosorption capacity, PCP can be used for cost-effective treatment of TCP from aqueous streams.Processes 2019, 7, 757 2 of 17 to develop cost-effective treatment strategy for the contaminated waste-water prior to release into the environment.The elimination of organic contaminants from the waste-water effluents using various methods like physical (membrane filtration, adsorption, biosorption and solvent extraction), chemical-biological oxidation, electrochemical oxidation, photocatalytic degradation, microbial degradation, ion exchange resins, catalytic oxidation, advanced oxidation processes have been proposed in the recent literature [9][10][11][12]. Among these techniques, the biosorption using various agricultural wastes has been thoroughly investigated for the elimination of organic contaminants and heavy metals from the standpoint of cost-effectiveness and eco-friendly considerations [13][14][15][16][17]. Several studies proved biosorption is a simple yet effective method for the elimination of pollutants, in which the significant factor is the utilization of agricultural wastes. Many authors highlighted the fact that the biosorption of phenol and phenolic derivatives using lignocellulosic residues and agricultural by-products do not require recycling and regeneration studies due to their low-cost and abundant availability in nature [2,[18][19][20][21].Pine trees annually produce large amounts of pine cones as an agricultural waste. Each cone consists of an axis, which is composed of several woody scales arranged in a spiral fashion. These scales comprise of epidermal and a sclerenchyma cell, which is mainly composed of lignin, tannins, and rosin etc. besides cellulose and hemicelluloses in their cell wall structures [22]. Pine cone biomass have newly used for removing heavy metals, dyes, and phenols from aqueous media [23][24][25][26][27][28]. However, its use for removing chlorophenols from contaminated wastewater has not yet been reported in the literature.Despite being a co...

Phenolic compounds are priority pollutants with high toxicity even at low concentrations. In this review, the efficiency of both conventional and advanced treatment methods is discussed. The applicability of these treatments with phenol and some common derivatives is compared. Conventional treatments such as distillation, absorption, extraction, chemical oxidation, and electrochemical oxidation show high efficiencies with various phenolic compounds, while advanced treatments such as Fenton processes, ozonation, wet air oxidation, and photochemical treatment use less chemicals compared to the conventional ones but have high energy costs. Compared to physicochemical treatment, biological treatment is environmentally friendly and energy saving, but it cannot treat high concentration pollutants. Enzymatic treatment has proven to be the best way to treat various phenolic compounds under mild conditions with different enzymes such as peroxidases, laccases, and tyrosinases.

Most industrial waste discharges are often contaminated with phenolic compounds, which constitute a major source of water pollution owing to their toxicity and low biodegradability. Development of cost-effective treatment of such industrial wastewater is therefore of paramount importance. Towards this end, we explore the efficacy of Pine bark powder (PBP), which is an agricultural solid waste material, as a low-cost biosorbent without any pre-treatment, for the adsorptive removal of 2,4,6-trichlorophenol (2,4,6-TCP) from aqueous media. The PBP was thoroughly characterized and the effect of important adsorption parameters were examined in the present investigation. The batch equilibrium data were analyzed using well-known isotherm models. Freundlich isotherm model provided the best description of the equilibrium biosorption behavior. At 25 ± 1 °C, the maximum biosorption capacity (q max) was 289.09 mg/g, which is higher than most biosorbents reported in the literature while the removal as high as 97% was obtained. Moreover, the biosorption process was fast, attaining equilibrium in less than 120 min of contact. The Elovich model accurately described the kinetics data. In view of high biosorption capacity and fast removal rates, PBP can be used for an efficient and cost-effective treatment of 2,4,6-TCP contaminated wastewater.
