Facile fabrication and characterization of kraft lignin@Fe₃O₄ nanocomposites using pH driven precipitation: Effects on increasing lignin content.

ABSTRACT: This work offers a facile fabrication method for lignin nanocomposites through the assembly of kraft lignin onto magnetic nanoparticles (Fe₃O₄) based on pH-driven precipitation, without needing organic solvents or lignin functionalization. Kraft lignin@Fe₃O₄ multicore nanocomposites fabrication proceeded using a simple, pH-driven precipitation technique. An alkaline solution for kraft lignin (pH 12) was rapidly injected into an aqueous-based Fe₃O₄ nanoparticle colloidal suspension (pH 7) under constant mixing conditions, allowing the fabrication of lignin magnetic nanocomposites. The effects of increasing lignin to initial Fe₃O₄ mass content (g/g), increasing in ratio from 1:1 to 20:1, are discussed wit
