Abstract

Background and purpose: 2, 4-dinitrophenol (2,4-DNP) is categorized as one of the priority pollutants that is used in pharmaceutical and chemical industries, pesticides, etc. In this study we aimed at investigating the BIODEGRADATION of 2,4-DNP by immobilized LACCASE on NANO-POROUS SILICA beads.Materials and methods: An experimental study was conducted in which the enzyme was chemically cross-linked on the NANO-POROUS SILICA beads. Temperature (40-60oC), contact time (2-12 h), mediator concentration (1-3 mM), pH (4-6) and initial pollutant concentration (10-30 ppm) were considered. The high performance liquid chromatography was applied to measure the degradation of the pollutant.Results: The maximum removal of 2,4-DNP (91%) was achieved at T=50oC, 2,4-DNP concentration of 10 ppm, mediator concentration of 1 mM, pH=5 and 12h contact time. ANOVA analysis showed that contact time and pH had the most and lowest effect on the process efficiency, respectively.Conclusion: 2,4-DNP was effectively degraded by LACCASE. The reusability and resistibility of the enzyme improved through immobilization. The immobilized LACCASE on NANO-POROUS SILICA beads could be applied to remove a wide range of phenolic pollutants.
