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].

The release of cobalt‐60 and cesium‐137 in the environment is considered dangerous pollutants. In this concern, the present work deals with gamma radiation‐induced synthesis of novel polyaniline/CuWO4 (PANi/CWO) nanocomposite adsorbent and estimating its potential adsorption capacity for cobalt‐60 and cesium‐137 from aqueous solution. The crystallite size of pure CWO NPs and PANi/CWO nanocomposite is found in the nanoscale range. Also, SEM images and XRD results confirmed the successful preparation of PANi/CWO nanocomposite. Further, the elemental mapping images proved that all the investigated elements were homogeneously distributed over the PANi/CWO nanocomposite. Besides, the adsorption experiments were conducted separately to investigate the adsorption behavior of cobalt‐60 and cesium‐137 by PANi/CWO nanocomposite. Adsorption processes have also been performed, and numerous factors, including medium pH, contact time, initial metal ion concentration, and temperature, have been tested. Batch experiments were done to get the optimum conditions for removing cobalt‐60 and cesium‐137. Four kinetic models were investigated, indicating that the adsorption process of cobalt‐60 and cesium‐137 onto PANi/CWO nanocomposite is controlled by chemisorption and intra‐particle diffusion. Four equilibrium isotherm models were investigated, revealing that the adsorption process is a monolayer and multilayer process on a heterogeneous surface. The (∆Ho) value suggested that this study's removal of cesium and cobalt has an endothermic behavior, whereas the positive (∆So) value proved that the examined system is random. The effect of temperature was investigated, and the calculated thermodynamic parameters indicated that the removal of cobalt‐60 and cesium‐137 by PANi/CWO nanocomposite has an endothermic behavior.

“…It emerges as one of the most challenging fission products to handle, due to its short-to-medium half-life (30 years) [4][5][6][7][8][9][10][11][12]. Caesium-137 was released into the environment during nearly all nuclear weapon tests and certain nuclear accidents, notably the abovementioned Chernobyl and Fukushima Daichii disasters [6,[13][14][15][16]. Not only major accidents, but also numerous minor incidents contribute to the radioactive contamination of our environment according to the literature published under [3][4][5][6]8,9,17,18].…”

This study investigates the adsorption of selected water pollutants, namely caesium and copper, by using natural zeolite of the clinoptilolite type, as well as clinoptilolites coated with MnOx, FeO(OH)-MnOx and FeO(OH). A comprehensive evaluation of these processes was conducted. The kinetics of Cs and Cu adsorption on all examined samples smoothly followed the pseudo-second-order kinetic model, with the liquid film step regarded as the slower step in both cases. The Langmuir isotherm model provided the most accurate description of Cs and Cu adsorption for all examined samples. However, when considering natural clinoptilolite and FeO(OH)-clinoptilolite systems in relation to Cu(II), the Redlich–Peterson model slightly outperformed the Langmuir model. The modification of clinoptilolite with Mn and Fe oxyhydroxides did not significantly enhance the removal efficiency of Cs compared to the unmodified sample. In contrast, the adsorption capacity, especially for MnOx-clinoptilolite, increased fourfold for Cu and other tested cations such as Pb and Zn, indicating improved efficiency in these cases.
