Embodiment 1
[0030] A method for detecting dihydroxybenzene isomers, comprising the steps of:
[0031] (1) Preparation of three-dimensional hierarchical porous carbon materials: polychitosan and Na with a mass ratio of 2:1 2 CO 3 Grind them in a mortar to mix them evenly, then place them in a corundum ark, put them into a tube furnace, pass through nitrogen at a certain flow rate for 1 hour to remove the air, then raise the temperature to 900°C at a heating rate of 3°C / min and keep it for 1h. The carbon material was obtained after natural cooling. Under magnetic stirring, the carbon material was immersed in 80°C hot water for washing to dissolve inorganic impurities. The material was washed three times repeatedly and dried at 100°C for 12 hours to obtain a three-dimensional hierarchical porous carbon material. CS-Na 2 CO 3 ;
[0032] (2) Preparation of modified electrode: Disperse the three-dimensional hierarchical porous carbon material prepared in step (1) into N,N-dimethylformamide,...
