Hettich MIKRO 120 Microliter Centrifuge Used in Separating Residue from Paper Template Samples
Environmental Engineering Science published a study entitled “Catalytic Activity of Biomorphic α-MoO3 in the Degradation of Methyl Violet Dye,” in which the Hettich MIKRO 120 microliter centrifuge was used for separating residue in the prepared sample solution.
Scientist Zhenyu Diao’s team explored the degradation of methyl violet (MV) found in a porous paper template sample using a mixture of combined orthorhombic molybdenum trioxide (MoO3) and TIO2 under a UV and visible light. It was reported that the procedure could degrade the organic pollutant MV and enhance hydroxyl radical OH production from water that would catalyze a reaction allowing it to undergo mineralization.
Prepared samples had their structures and photocatalytic performances identified, and the resulting residue was centrifuged at 10,000 rpm for 20 minutes using the Hettich MIKRO 120.
Absorption spectra samples were then recorded, and a formula was created to express MV degradation. The study concludes that 3mg of the biomorphic α-MoO3 could degrade 90% of an MV aqueous solution with a concentration of 20 mg/L under normal visible light, and that α-MoO3 grain size and porosity were factors that affected catalytic performance.
Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on catalytic activity. The Hettich MIKRO 120 is a powerful, ultra-compact microliter centrifuge that is safe, quiet and reliable.
