摘要:

9,10-Anthraquinone (AQ), anthraquinone-2-sulfonic acid (AMS), and anthraquinone-1-acetic acid (AMA) were determined in alkaline pulping liquors by adsorption on Amberlite XAD-2 from liquors diluted with ethanol (AQ) or water (AMS and AMA). After washing, AQ was eluted with 99% ethanol, AMS with acidified 25% ethanol and AMA with alkaline 25% ethanol.
