Special Issue Information

Dear Colleagues,

Various sources of pollutants can increase the levels of heavy metals in different environmental compartments. Potentially toxic metals sources for the soil can be lithogenic or anthropogenic. Anthropogenic activities due to rapid urbanization and industrialization could result in the release of high quantities of undesirable potentially toxic metals into the environment. Generally, potentially toxic metals are considered the most dangerous contaminants because of their non-degradability and long-term persistence in the environment. Potentially toxic metals may be released into the environment through vehicle emissions, by chemical industries, mining activities, coal combustion, in municipal solid waste, and as dust particles deposited onto the soil surface. Therefore, it is essential to develop sustainable approaches (including the development of new toxic metal-immobilizing agents) to manage and rehabilitate metal-contaminated soils.

This Special Issue aims to collect and present breakthrough research on the remediation and rehabilitation of metal-contaminated soils. The scope of this Special Issue covers but is not limited to the following topics:

  • Soil remediation techniques including in situ immobilization;
  • Industrial and mining soils remediation and rehabilitation;
  • Development of new immobilizing agents based on clay minerals and bio-amendments for the immobilization and rehabilitation of metal-contaminated soils and the improvement of their quality;
  • Biochar and its modified forms as valuable soil additives for in situ immobilization of potentially toxic metals;
  • Biochar modification as a remediation technology for the sustainable management of metal-contaminted soils.

The production of biosorbents by waste biomass has attracted considerable attention due to the low cost and abundance of the raw materials. Here biochar produced from Eucalyptus camdulensis sawdust (EU-biochar) via pyrolysis at 600 °C was used as a potential biosorbent for Ni2+ and Pb2+ metal ions from wastewater. Characterization experiments indicated the formation of C- and O-bearing functional groups on the EU-biochar surface, while shifts and changes in the shape of C–H bands suggested the adsorption of Ni2+ and Pb2+ onto EU-biochar by interacting with surface carboxylic groups. Pb2+ was adsorbed more quickly than Ni2+, indicating a faster and stronger interaction of Pb2+ with EU-biochar compared to Ni2+. As the initial concentrations of both metal ions increased, the percentage removal decreased, whereas increasing the EU-biochar dose improved the percentage removal but impaired the adsorption capacity for Ni2+ and Pb2+. The adsorption capacity could only be improved without affecting the percentage removal of both ions by increasing the pH of the metal solutions. The sorption efficiency of EU-biochar and the removal mechanism of Ni2+ and Pb2+ were further explored using non-linear and linear forms of kinetic and isotherm models. Full article

Eucalyptus camdulensis biochar (Ec-bio) was used to adsorb crystal violet (CV) and methylene blue (MB) dyes, which was optimized and further evaluated using different isotherm and kinetic models. Microscopy and spectroscopy techniques showed the interactions of the dyes with the surface functional groups of the Ec-bio, resulting in the removal of the dyes from aqueous solution. Both dyes were immediately uptaken, with equilibrium reached in 60 min, with a higher sorption efficiency of CV compared to MB. Thermodynamic parameters showed endothermic adsorption and the nonspontaneous adsorption of both dyes onto the Ec-bio. Both the adsorption capacity and percentage removal increased with the increasing solution pH from 2.0 to 4.0 and to 10 for CV and MB. An increase in adsorption capacity was observed upon increasing the initial concentrations, with a corresponding decrease in the percentage removal. The pseudo-second-order (PSO) and Elovich kinetic models (nonlinear approach) were a good fit to the data of both dyes, confirming a chemisorptive adsorption process. The Langmuir isotherm fitted well to the CV data, supporting its monolayer adsorption onto the Ec-bio, while the Freundlich isotherm was a good fit to the MB dye data, suggesting the surface heterogeneity of the Ec-bio. The Dubinin–Radushkevich isotherm was a good fit to the adsorption CV data compared with the MB dye, suggesting the physisorption of both dyes onto the Ec-bio due to its mean free energy of adsorption of <8 kJ mol−1.
