Abstract:

A new research-based comprehensive experiment was introduced. Low-cost polyaniline-lignosulfonate (PAL) composite with high-adsorption performance was synthesized via a facile oxidative chemical polymerization from aniline monomers by using lignosulfonate as a dispersant. Students are required to master the experimental procedures of PAL composite synthesis, and systematically understand the methods of characterization and dye-adsorption performance measurements of PAL. Through this experiment, students can study and apply polymer chemistry, polymer physics, and functional polymer, as well as develop their comprehensive experimental abilities.

Key words: Research-based comprehensive experiment, Polyaniline-lignosulfonate composite, Oxidative chemical polymerization, Adsorption
