Rock Powder Applied in the Discoloration of Industry Dye of Molded Pulp Packages Effluent

In the present work, rock dust was evaluated as an adsorbent and heterogeneous photocatalyst in discoloration of Basazol Yellow 46 L dye, which is widely used dyeing molded pulp packages. Although produced large quantities quarries a byproduct exploration, little known about its application photocatalyst. Rock characterized by XRD, SEM/EDS, photoacoustic spectroscopy, N2 physisorption had photocatalytic activity assessed through phenol salicylic acid degradation tests. The characterization results showed that mainly composed silica alumina triclinic structure, has bandgap energy 2.36 eV, specific area 1.5 m2/g. proven to be photocatalytically active tests also presented adsorptive capacity for effluent containing dye.
