Abstract: The effects of potassium citrate, potassium tartrate and hydrochloric acid on heavy metals removal from peanut meals were compared, and the variation of nutrient elements and crude protein concentrations before and after extraction were studied. The results showed that the removal rate of Pb, Zn, Cu and Cd in peanut meals gradually increased with the increase of extraction time and concentrations of extractants. The remaining Cd content in the meal under the extraction via 0.50% and 1.00% hydrochloric acid were only 0.42 mg/kg and 0.34 mg/kg, respectively. After three successive extractions with the three kinds of extractants, the removal rate of Zn and Cu was greatly improved. The residual Cd concentrations in the meal with the third extraction of 30 mmol/L potassium tartrate and the second extraction of 0.25% hydrochloric acid were 0.36 and 0.21 mg/kg, respectively, both meeting with the requirements of Hygienical standard for feeds (GB 13078-2017). It was noticeable that potassium citrate and potassium tartrate could remove heavy metals with less losing of nutrient elements. Low-concentration hydrochloric acid could extract a large amount of nutrient elements and they all had little effect on crude protein. According to the comprehensive consideration, the low-concentration hydrochloric acid was more appropriate to peanut meal heavy metal extraction.
