ZIF-L(Co)crystals were used as the template,and polyimide P84 was employed as the polymer to prepare the derived carbon materials based on ZIF-L(Co)doped P84(ZIF-L(Co)@P84)with different carbonization temperatures as variables.The ZIF-L(Co)@P84 derived carbon materials were characterized using SEM,FTIR,XRD,TGA,and dye adsorption tests were conducted.The results showed that the ZIF-L(Co)@P84 derived carbon material carbonized at 650 ℃ exhibited the best adsorption performance when the adsorption time was 8 hours.It achieved a dye adsorption rate of 94.269％for methylene blue and 64.629％for methyl orange,demonstrating excellent adsorption performance and certain selectivity towards methylene blue.
