Conclusion

This review shows that CDs are a versatile tool for environmental remediation because CD chemistry offers various possibilities for preparing various CD derivatives (monomers and polymers) or materials (grafted or coated). CDs can be used in all areas of remediation technologies including soil, groundwater, wastewater and atmosphere. The number of papers that appears each year in the literature shows recent and continuing interest in applications of CDs in environmental protection. The large-scale commercialization of CDs and CD derivatives leads to a reduction of the cost, favorable to environmental applications. The future of CDs and CD derivatives in environmental remediation seems to be bright.
