Removal of Methylene Blue Dye by Basalt Quarry Dust Waste from Buriram Crushing Plant

Removal of Methylene Blue Dye by Basalt Quarry Dust Waste from Buriram Crushing Plant

This present research aims to investigate the removal availability of methylene blue (MB) by basalt quarry dust waste from Buriram rock mining of Industrial, without chemical activation and calcination, inexpensive and readily available as absorbent. The factors influencing the adsorption capacities, i.e. adsorbent dosage, contact time, an acid-base of solution, initial dye of methylene blue concentration, and temperature, were studied. The results of the study showed that the adsorption capacities of dye adsorption by basalt quarry dust was 0.83 mg/g, and adsorption percentage was 83.37 with 0.5 g adsorbent dosage. The adsorption was approached into equilibrium within 60 minutes. Furthermore, the adsorption isotherm of the dye was well fitted with the Langmuir models (R2 = 0.997). The results showed well-done of adsorption percentages and adsorption capacity in all acid-base of solutions. The trend of adsorption capacity was increased by expanding methylene blue concentration and temperature. The results of this research indicated that the basalt quarry dust would be applied to be an environmentally friendly adsorbent for organic dye adsorption.
