Poly(butyl methacrylate)‐grafted alginate/Fe3O4 nanocomposite: Synthesis and its application for removal of dyes

“…[21,22] Mechanical and thermal characteristics of the adsorbents are improved substantially by introducing nanoparticles due to greater area of contact available between the nanoparticle and the polymer. [23][24][25] Several research studies have recently been conducted to investigate elimination of pollutants from wastes by using inexpensive polysaccharides (biopolymers) 26 as these substances are readily available, biocompatible, nontoxic, and inexpensive. Alginic acid or alginates (salts of alginic acid) are polysaccharides found in the cell walls of many species of algae.…”
