We report the simultaneous adsorption of acid blue 25 dye (AB25) and heavy metals (Zn2+, Ni2+ and Cd2+) on a low-cost activated carbon, whose adsorption properties have been improved via a surface chemistry modification using a calcium solution extracted from egg shell wastes. Specifically, we have studied the removal performance of this adsorbent using the binary aqueous systems: AB25 - Cd2+, AB25 - Ni2+ and AB25 - Zn2+. Multi-component kinetic and equilibrium experiments have been performed and used to identify and characterize the synergic adsorption in the simultaneous removal of these pollutants. Our results show that the presence of AB25 …

In this paper, we report the competitive removal of Pb, Cd and Ni ions from binary metal solutions using chicken feathers. These heavy metals are very toxic for human being and are present in wastewaters of several industrial activities. Therefore, multi-component sorption studies are required to identify the capabilities and limitations of chicken feathers as low-cost sorbent for the simultaneous removal of these metal ions from wastewaters. To the best of our knowledge, sorption equilibrium studies involving chicken feathers and Pb, Cd and Ni in binary aqueous solutions have not been reported. Therefore, the binary sorption data for systems Pb …

This chapter provides an overview of the application of activated carbons obtained from lignocellulosic precursors for wastewater treatment. Analysis and discussion are focused on the performance of different activated carbons obtained from several precursors and their advantages and capabilities for the removal of relevant toxic compounds and pollutants from water.

The activated carbon is the universal adsorbent used in the removal of water pollutants such as dyes, heavy metals, fluoride and arsenic, among others. The commercial activated carbons are generally obtained from wood and coconut shell. However, in recent years, other lignocellulosic materials have been used as precursors in the synthesis of this adsorbent for specific applications. This book discusses and analyzes key aspects concerning to the preparation, characterization and application of activated carbons obtained from different lignocellulosic materials. Based on the fact that the activated carbon is used in a broad variety of treatment systems, this book will be …

We report the removal of zinc ions from aqueous solution by raw chicken feathers using both batch and continuous systems. Specifically, kinetic and sorption isotherms have been determined considering the effect of temperature, pH and metal concentration. Batch sorption data were fitted to various sorption models and results indicate that Zn2+ sorption process using raw chicken feathers followed the pseudo-second order rate model, while sorption isotherms were described properly by Sips isotherm. Sorption isotherms show that the experimental maximum sorption capacity of Zn2+ was found to be 4.31 mg/g at 30 °C and pH 5 and that chemisorption may play …

The pecan nuts are widely cultivated in states of north of Mexico and the residues generated during nut processing are abundant and not reused. In the present study, the pericarp of pecan (PP) was physicochemically characterized and their use as low cost biosorbent of lead and acid blue 25 was studied in batch systems at different experimental conditions. Also, the PP was used as precursor of activated carbon and a natural modifier agent extracted from egg shells was used in the synthesis of the carbons. Results suggest that the pericarp of pecan (PP) has an acidic character due to the …

We introduce the application of hen egg shell waste to improve the adsorption capacities of heavy-metal ions using commercial carbons via the modification of their surface chemistry. Specifically, a calcium solution extracted from egg shell waste has been used as a low-cost activation agent to improve the adsorption properties of three commercial carbons. An orthogonal array of the Taguchi method has been applied to identify the optimal conditions for the adsorbent modification process using the Zn batch adsorption, at 30 °C and pH 5, as the response variable. Our results show that maximum adsorption capacities of Cd, Ni, and Zn …

Chicken feathers were used as biosorbent for Pb removal from aqueous solution. In this paper, the kinetics and equilibrium studies at several pH, temperature, and metal concentration values are reported. For tested conditions, the Pb sorption capacity of this poultry waste ranged from 0.8 to 8.3 mg/g. Optimal conditions for Pb removal by chicken feathers have been identified. Pseudo-first order and pseudo-second order equations were used to analyze the experimental data. In addition, the sorption isotherms were fitted to classical Langmuir and Freundlich models. Finally, thermodynamic parameters for the sorption process have been determined. In summary, the results showed that …
