The invention provides a method for removing carbon impurities in amorphous alloy. By the adoption of the method for removing the carbon impurities in the amorphous alloy, the problems that according to a method for removing impurities in amorphous alloy in the prior art, secondary pollution can be caused, and the impurity removal effect is poor are solved. The method for removing the carbon impurities in the amorphous alloy comprises the following steps that S1, the amorphous alloy with the carbon impurities needing to be removed is provided; S2, an impurity removal agent and the amorphous alloy are mixed, so that a mixture is obtained, wherein the impurity removal agent contains a carbon removal agent which is the oxide of a carbon removal metal element, the carbon removal metal element is one of elements contained in the amorphous alloy, and the melting point of the carbon removal agent is lower than the melting point of the amorphous alloy; and S3, the mixture is melted in a protective atmosphere, and then vacuumizing treatment is conducted. According to the method for removing the carbon impurities in the amorphous alloy, the carbon impurity removal effect is good, and secondary pollution caused by introduction of new impurities is avoided.
