Special Issue Information

Dear Colleagues,

Water resources are closely related to the survival and development of human society. Various contaminants in water pose serious threats to the environment and human health due to the pollution of water resources worldwide, and the development of remediation technologies for water treatment is of vital importance. Adsorption, which has the merits of easy operation and absence of by-products, has long been used for water treatment. Oxidation is also a widely employed technology for water treatment. Especially, advanced oxidation processes (AOPs), including ozone-based, photocatalytic, electrocatalytic, Fenton, persulfate-based and other processes, are receiving increasing attention. Although water treatment by adsorption and oxidation has been investigated extensively, more research in this area is still in urgent demand. On the one hand, various types of new materials have been developed recently, and their potential applications in this area may bring new possibilities. On the other hand, most of the works are focused on investigations at laboratory scale, and further tests in pilot-scale or even larger systems are needed. Moreover, adsorption and oxidation should not be considered as distinctly separated processes. For example, adsorption is generally involved in the heterogenous catalytic oxidation process, and the adsorptive performance of a certain catalyst has been found to be closed related to its catalytic activity. Oxidation can also play a part in adsorption processes, which can be used for the  pretreatment of wastewater as well as regeneration of the adsorbents. Therefore, this Special Issue is intended to provide an integrated view of the trends in solving the problems associated with adsorption and oxidation processes for water treatment.

In this Special Issue, original research articles and reviews are welcome. Potential topics include but are not limited to the following:

  • Applications of new types of materials for adsorptive or oxidative water treatment, including CNT, graphene, LDH, MOF, COF, MXene, black phosphorus, etc.
  • Water treatment by adsorption or oxidation in pilot-scale and larger systems.
  • Integrated water treatment processes coupling adsorption and oxidation.
  • Investigations on the contribution of adsorption in catalytic oxidation systems.
  • Application of adsorption or oxidation for removal of emerging contaminants from water resources.
  • Adsorption or oxidation processes coupled with other processes (e.g., membrane, coagulation, MBR) for water treatment.
  • Selective or synergistic treatment of certain contaminants by adsorption or oxidation.

We look forward to receiving your contributions.

The adsorption characteristics of calcareous sand for heavy metals Pb(II), Cu(II) and Cd(II) have been studied by batch testing in this study. The influence of the solid–liquid ratio, initial pH0 value, ionic strength, reaction time, temperature and initial concentration on adsorption has been investigated. Test results indicate that the initial pH and the solid–liquid ratio have a significant influence on the removal efficiency. At T = 30 °C, r = 1.0 g/L, and C0 = 1000 mg/L and for 12 h of reaction, the removal efficiencies of Pb(II), Cu(II) and Cd(II) are 97.6%, 88.15% and 65.72%, respectively. The adsorption quantity is more than 80% of the maximum adsorption quantity within 60 min, and the equilibrium adsorption can be reached within 120 min. The pseudo-second-order kinetic model is suitable to simulate the dynamic adsorption process of calcareous sand, and the isothermal process is found to obey the Langmuir model. Calcareous sand has a very high adsorption capacity for Pb(II), Cu(II) and Cd(II), with a maximum adsorption quantity Qm reached 1052.95 mg/g, 1329.84 mg/g and 1050.56 mg/g, respectively. Thermodynamic test results indicate that the adsorption process is spontaneously exothermic and that low temperature is favorable to the adsorption reaction. Full article

The development of simple, effective, economical, and environmentally friendly methods for removing hazardous substances of anthropogenic origin from aquatic systems is currently one of the greatest challenges, among others, due to the variety of pollutants and the transformations they may undergo in the environment. In recent years, there has been an increased interest in adsorption methods based on the use of natural polymers, including non-toxic chitosan (CS), which is characterized by good coating properties, biocompatibility, and biodegradability. This review concerns the latest developments (since 2019) in the application of novel chitosan-based materials for the removal of hazardous substances (e.g., metal and metalloid ions, synthetic dyes, pharmaceuticals) from aqueous solutions, with particular emphasis on their most important advantages and limitations, as well as their potential impact on sustainability.

The performance stability and regeneration property of catalytic membranes should be considered from a practical viewpoint. In this review, recent works concerning this issue have been comprehensively summarized. The performance stability of catalytic membranes was first summarized in terms of the two commonly employed evaluation ways, i.e., multi-cycle experiments and long-time filtration. The main deactivation reasons included the adsorption of pollutants and its oxidation intermediates, the change in chemical properties of the membranes, as well as leaching of metal species. After that, the regeneration property of the catalytic membranes was discussed according to the different regeneration methods including solvent washing, heat treatment, advanced oxidation, and others. This review further highlights the current achievements and hurdles in the performance stability and regeneration property of catalytic membranes and proposes recommendations for future works, including more attention on changes in the kinetic constant, trans-membrane pressure/flux and removals of total organic carbon/chemical oxygen demand, the selection of suitable cycle numbers and operation time, the development of new regeneration methods, as well as more studies on the pilot and larger scales.
