[0047] figure 2 The dotted line in the middle represents the ultraviolet-visible spectrum of catechol degraded by tyrosinase; the solid line represents the synergistic degradation of phenol by 1-ethyl-3-methylimidazolium alanine ionic liquid and tyrosinase The ultraviolet-visible spectrum of catechol, the reaction time from bottom to top is 0, 4, 8, 12, 16, 20 minutes;
[0048] image 3 Curve a in the middle represents the time-absorption intensity diagram of catechol degraded by tyrosinase, and curve b represents 1-ethyl-3-methylimidazolium alanine ionic liquid and tyrosinase synergistically catalyze the degradation of phenol to generate Time-absorption intensity plot of catechol.
[0049] 1. Preparation of 1-ethyl-3-methylimidazole-alanine ionic liquid
[0050] 1) First, take equimolar ratio of bromoethane and nitrogen methyl imidazole into a round bottom flask, react at 50°C for 3 hours, then evaporate and remove the water in a vacuum, and prepare the ionic liquid inter...
