description | The invention discloses a method for detecting the content of rare earth in suspension liquid after neodymium iron boron cutting, and relates to the technical field of rare earth detection. The method comprises the following steps: heating a ceramic crucible to a constant weight, pouring a suspension collected after cutting neodymium iron boron into the ceramic crucible, weighing, pouring the suspension in the ceramic crucible onto filter paper of a suction filtration device for suction filtration, and carrying out vacuum drying on the filter paper to a constant weight; performing vacuum drying on the filter paper subjected to suction filtration and a sample on the filter paper to constant weight, and collecting a solid sample; and finally, digesting the solid sample by using aqua regia, carrying out rare earth component detection by using iron as a matrix solution by adopting inductively coupled plasma emission spectrometry, and calculating the content of rare earth elements in the suspension by combining th |
