Method for reducing content of heavy metals in Chinese herbaceous peony root extract by using double-fat active adsorption method

The invention belongs to the technical field of extract treatment, and provides a method for reducing the content of heavy metals in a Chinese herbaceous peony root extract by using a double-fat active adsorption method, which comprises the following steps: S1, raw material preparation and acid-base pretreatment; s2, crushing and extracting; s3, filtering and concentrating; s4, heavy metal double-grease adsorption treatment; s5, purifying and refining; s6, drying for determination; according to the method, heavy metal ions in the Chinese herbaceous peony root extract can be specifically adsorbed by adopting a double-fat active adsorption method, the removal rate reaches up to 80% or above, and meanwhile, the high recovery rate of effective components is kept; compared with a traditional heavy metal removal method, the method does not generate a large amount of waste, the adsorption resin can be regenerated and recycled, environmental pollution and resource consumption are reduced, and through comprehensive pu
