Removal of triphenylmethane dyes by calcium carbonate–lentinan hierarchical mesoporous hybrid materials

摘要: Abstract An inorganic–organic hybrid material with hierarchical mesoporous structure was prepared by involving lentinan (LTN) into CaCO3 crystal using a simple method at mild condition. The characterization of CaCO3–LTN materials indicated that it has higher surface area, more adsorption sites and better dispersion in water compared to bare due rich organic ligands LTN structure. applied the removal triphenylmethyl dyes (TPMs) including violet (CV), malachite green (MG) aniline blue (AB). A powerful capability observed, moreover, found very rapid efficient oxidative degradation H2O2 can be achieved assist reactants concentrated its plentiful negative charged pores. CV, MG, AB complete decolorized H2O2 + CaCO3–LTN after 30 min, 10 min, 2 min, respectively. Moreover, cation dyes, besides TPMs, were also suitable treated this system. These results ensure promising candidate for treatment effluent textile industry.
