AB  - In the present work, a type of biochar materials derived from carbonizing peanut 
      shells were obtained and employed as the adsorbents of pipette-tip solid-phase 
      extraction (PT-SPE) for the enrichment and determination of six 
      endocrine-disrupting phenols (EDPs) in combination with high-performance liquid 
      chromatography equipped with ultraviolet detector (HPLC-UV). Abundant aliphatic 
      and aromatic carbon structures and functional groups from polar heteroatoms (N, 
      O, S) were distributed in the low-cost and eco-friendly peanut shells-derived 
      biochar materials and were favorable for the enrichment of target EDPs. Moreover, 
      the theoretical calculation based on density functional theory (DFT) proved that 
      the effective enrichment of EDPs in aqueous samples benefited from the effective 
      adsorption on the peanut shells-derived biochar materials. The experimental 
      factors influencing the extraction efficiency were investigated, including 
      adsorbent amount, aspirating/dispensing cycles, the type of elution solvent and 
      elution times, salt addition, sample solution pH and type and volume of washing 
      solvent. Under the optimal conditions, the proposed PT-SPE method exhibited good 
      linear relationship (R(2) > 0.993) in the range of 0.5-400 microg/L and low limits of 
      detections (LODs) from 0.25 to 2.5 microg/L, as well as good precision and accuracy 
      with relative standard deviations (RSDs) of 0.3%-13.2% and recoveries of 
      83.5%-117.1%. Finally, the biochars-based miniaturized pretreatment method was 
      employed for the determination of six EDPs in bottled water, milk, tea beverage 
      and disposal plastic bag soaked solution with recoveries from 77.5% to 116.5%.
