NOVELTY - Processing alizarin red wastewater by adsorption and photocatalysis comprises adding 4-16 mg adsorption-photocatalyst per 10 ml to alizarin red wastewater containing 25-300 mg/l, processing at pH of 3-6 and at 10-50°C under natural illumination condition for 2-5 hours, where the adsorption-photocatalyst is polyaniline (PANI)/carbon nanotubes (CNTs) composite material or PANI/graphite oxide (GO) composite material, where PANI/CNTs composite material is prepared by ultrasonically mixing water, D-camphorsulfonic acid, aniline, aniline dimer and carbon nanotubes to obtain mixed solution, mixing the mixed solution with ammonium persulfate and reacting, where PANI/GO composite material is prepared by ultrasonically mixing water, D-camphorsulfonic acid, aniline and aniline dimer to obtain mixed solution, adding ammonium persulfate, mixing and reacting to obtain polyaniline nanofibers, and adding polyaniline nanofibers and carboxylated graphene oxide into water to blend and react. USE - The method is useful for processing alizarin red wastewater by adsorption and photocatalysis. ADVANTAGE - The method: prepares PANI/GO and PANI/CNTs composite materials through a simple preparation method; is used for treating alizarin red dye wastewater by combining adsorption and photocatalysis; and has high removal rate of dye wastewater, and alizarin red removal rate by PANI/CNTs composite material reaching more than 90%.
