    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.

    Modern Applications of Ferrites: An Important Class of Ferrimagnetic System
    (Springer Science and Business Media Deutschland GmbH, 2021-10-29T00:00:00) Gomes, Gabriel Alves; Akhtar, Kanwal; da Costa, Gisela Lara; Javed, Yasir; Sharma, Surender K.
    Magnetic nanoparticles (MNPs) have been used in engineering applications for different purposes in the last few decades, increasing their relevance recently on biomedical studies, with alternative treatments to most complex diseases, and microelectronic fields, as an excellent way to improve aspects such as thermal and electric conductivity. The use of nanomagnetic ferrite particles in cancer therapy and to control antibacterial agents is also noteworthy, because of their advantages in terms of resistance to temperature variations, chemical stability, and long-term durability. One of the promising applications of these nanoparticles includes water-purifying systems. In this chapter, those outstanding aspects of nanoparticle ferrites were treated since their very applicable point-of-view. In this sense, the structure properties of this class of materials are a very important matter to discuss, investigating how their unique ferrimagnetic face centered behavior could directly influence their potential in technological fields and innovative medical treatments. � 2021, Springer Nature Switzerland AG.
