Abstract: Based on molecular imprinting technology, a new molecular imprinted adsorption membrane has been prepared using waste mycelium from industrial fermentation as the main component. The adsorption characteristics and the factors influencing the performance and stability of the membrane were studied. The results showed that the maximum static adsorption capacity for Cr(III) was about 65mg/g when the optimum pH of 6 was chosen. The breakthrough time reached 400min and the dynamic adsorption capacity was about 27mg/g. The adsorption process could be fitted to the Langmuir isotherm model. This novel adsorption membrane shows good stability and can be reused up to 60 times without losing its uptake ability
