Nanoparticles of magnetic fluids are stabilized with various surfactants. Lignosulfonates are water-soluble byproducts of sulfite pulping process. The aim of our work is to estimate possibility of using nitrated lignosulfonates for stabilization of water-based magnetic fluid and determine optimal nitration conditions. Nitrolignosulfonates were synthesized by nitration of sodium lignosulfonates with nitric acid and the products without further purification were used for preparation of magnetic fluid. Magnetic nanop...
