Method for fast determining cadmium in traditional Chinese medicine materials

The invention discloses a method for fast determining cadmium in traditional Chinese medicine materials.The method includes: crushing traditional Chinese medicine material samples, placing into a centrifugal tube, adding inorganic acid solution, performing vibrating extraction, taking filtrate, adding complex masking agent and surfactant, well mixing, and adding color developing agent for color developing so as to determine the cadmium.The method has the advantages that the method is simple to operate, accurate in determination, suitable for any sites and high in sensitivity, and the lowest detection limit of the method is 4.0microgram.L. 本发明公开了种快速测定中药材中镉的测定方法，通过将中药材样品粉碎后，放入离心管中，加入无机酸溶液，振荡提取后，取滤液，加入联合掩蔽剂、表面活性剂，混匀后，加入显色剂显色进行测定。本发明方法操作简单，测定准确，适合任何场所，且灵敏度高，最低检测限为4.0μg·L。
