A Perspective on Environmental and Disposal Assessment of Magnetic Sorbents

While adsorption is an age-old technique for the treatment of contaminated water, the involvement of magnetic phase separation is relatively new. Magnetism in adsorbents (or magnetic adsorbents) has eased the recovery of micro/nano-adsorbents post-adsorption. Magnetic adsorbents could lower the operation time/cost and improve the overall efficacy of the adsorption process. In this book, most of the chapters have highlighted the use of magnetic adsorbents in water remediation applications. This chapter is focused on the regeneration strategies and disposal assessment of magnetic adsorbents and eluents post-exhaustion. Moreover, the chapter has been updated with some accounts of repurposing strategies for exhausted magnetic adsorbents.
