TL;DR: In this article, the removal of chromium(VI) ions from aqueous solution using Limonia acidissima (wood apple) shell activated carbon was studied using linear Freundlich and Langmuir adsorption isotherm models to describe the experimental equilibrium isotherms.
Abstract: The removal of chromium(VI) ions from aqueous solution was studied using Limonia acidissima (wood apple) shell activated carbon. The removal extent was found to be a maximum at a pH value of 2, with the lowcost adsorbent having an adsorption capacity of 13.74 mg/g. The material employed was characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and elemental analysis. The linear Freundlich and Langmuir adsorption isotherm models were applied to describe the experimental equilibrium isotherms. The results showed that the Langmuir equation gave a better fit to the experimental data than the Freundlich equation. The pseudo-first-order and pseudo-second-order models were applied to the adsorption kinetics of Cr(VI) ions onto wood apple shell activated carbon. Thermodynamic parameters such as the standard enthalpy (ΔH0), the Gibbs' free energy (ΔG0) and the standard entropy (ΔS0) were evaluated and indicated that the sorption process was spontaneous and endothermic...

TL;DR: In this article, a detailed list of production methods of activated carbon from wood biomass is presented systematically, and an attempt has also been made to review the physical properties, such as ultimate and proximate analyses of wood biomass material.
Abstract: Activated carbon has been an ideal material for the separation of a variety of chemical pollutants. Its extensive use is limited due to the cost of production, which has triggered the researches on the viable option for the non-conventional and cost-effective production. The application of biomass waste has been widely explored as an alternative to expensive methods of activated carbon production from coal. In this study, detailed list of production methods of activated carbon from wood biomass is presented systematically. The attempt has also been made to review the physical properties, such as ultimate and proximate analyses of wood biomass material. Further, the chemical compositions of wood, such as hemicelluloses, cellulose, and lignin are also dealt with. Finally, this review incorporates the existing research papers on wood-derived activated carbons to understand the influence of pyrolysis temperature, activation temperature, and effect of various physical and chemical activation conditions on the production, surface characteristics and adsorption behavior of activated carbons. The outcome of this study revealed that the activated carbons from wood biomass exhibit promising characteristics in terms of surface area, pore size and pore volume, surface functional groups, and surface entrapment behavior against various water soluble chemical toxicants.

TL;DR: In this paper, a review of different textile industry processes, wastewater generation, its nature and chemical composition, environmental impacts and health hazards and treatment approaches available for TIWW treatment is presented.
Abstract: Textile industry wastewater (TIWW) is considered as one of the worst polluters of our precious water and soil ecologies. It causes carcinogenic, mutagenic, genotoxic, cytotoxic and allergenic threats to living organisms. TIWW contains a variety of persistent coloring pollutants (dyes), formaldehyde, phthalates, phenols, surfactants, perfluorooctanoic acid (PFOA), pentachlorophenol and different heavy metals like lead (Pb), cadmium (Cd), arsenic (As), chromium (Cr), zinc (Zn) and nickel (Ni) etc. TIWW is characterized by high dye content, high pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS), total organic carbon (TOC), chlorides and sulphates. Thus, requires adequate treatment before its final discharge into the water bodies to protect public health and environment. The treatment of TIWW is a major challenge as there is no particular economically feasible treatment method capable to adequately treat TIWW. Therefore, there is a need to develop a novel, cost-effective and eco-friendly technology for the effective treatment of TIWW. This review paper emphasizes on the different textile industry processes, wastewater generation, its nature and chemical composition, environmental impacts and health hazards and treatment approaches available for TIWW treatment. It also presents various analytical techniques used to detect and characterize TIWW pollutants and their metabolites, challenges, key issues and future prospectives.
