    Magnetic Ferrites-Based Hybrids Structures for the Heavy Metal Removal
    (Springer Science and Business Media Deutschland GmbH, 2021-10-29T00:00:00) Abbas, Muhammad Khawar; Yasin, Effat; Sajid, Muhammad Munir; Shad, Naveed Akhtar; Akhtar, Kanwal; Manhas, Anita; Sharma, Surender K.; Javed, Yasir
    Adsorption is a major process for heavy metal removal and the research trend is focused toward the applications of new technologies in order to intensify the already existing processes. Intrinsic properties of magnetic materials (arrangement and surface-to-volume ratio) of adsorbate and adsorbent are critical for satisfactory results. Magnetic field strength plays an important role as it indicates the alignment of spins with the magnetic field to provide adsorbate mobility and generate heterogeneity at adsorbent surface. Applications of magnetic field for intensification of adsorption process provide environment friendly, safe and economic alternative. This chapter describes different types of magnetic ferrites-based hybrids for heavy metal removal. Surface modification of magnetic nanohybrids through different surface modification strategies and general adsorption mechanisms for different types of pollutants are discussed comprehensively. Major thrust of this chapter is to provide information about different features of magnetic ferrites for their potential application as adsorbent for heavy metal removal. � 2021, Springer Nature Switzerland AG.
