The Green Magnetism: Engineering a Ziziphus mauritiana-Derived Magnetite/Biochar Nanocomposite for Heavy Metal Adsorption from Wastewater

In the microscopic world of atoms and bonds, Noor Zulfiqar found a macroscopic calling: the restoration of our planet's most vital resource-water. This book traces the journey of a scientist who viewed the crisis of industrial pollution not with despair, but through the lens of nanotechnology. Within these pages, we explore the intersection of precision and passion. We delve into the methodologies that ranked her among the top scientists globally and the pedagogical philosophy she brought into the lecture halls of Pakistan. This is more than a record of scientific achievement; it is a blueprint for how the next generation of researchers can harness the power of green chemistry to engineer a cleaner, more sustainable future. Overall, this book presents an attractive route toward low-cost, reusable, and scalable wastewater treatment through the green synthesis of magnetite (Fe3O4) nanoparticles using Ziziphus mauritiana leaf extract and their integration with corncob-derived biochar to create a magnetic nanocomposite for the adsorptive removal of heavy metals, chromium(VI) and nickel(II), from contaminated water.
