摘　　要：为了研究自制的汉麻活性炭对竹醋原液的脱色脱臭的最佳工艺,以单因素试验考察活性炭的用量、吸附时间、温度对竹醋原液(100℃蒸馏液)脱色脱臭的影响.结果表明:最佳工艺条件为单位体积竹醋原液汉麻活性炭用量24mg/mL,单位体积竹醋蒸馏液汉麻活性炭用量10mg/mL,吸附20min,吸附温度60℃,pH值为3.0,磷酸汉麻活性炭脱色率达85%以上;氯化锌脱色率达60%以上,磷酸汉麻活性炭吸附量高达385.3～427.3mg/g.结论:磷酸汉麻活性炭脱色率比其他活性炭脱色、脱臭率高,可应用于竹醋液的脱色脱臭.The optimum process of decolorization and deodorization was studied, by using self-made hemp activated carbons and bamboo vinegar. The influence of adsorption dosage, time, and temperature on the decolorization and deodorization of bamboo vinegar liquid and its distillate（100℃） were explored by single factor. The results show that the optimum process conditions are. The hemp activated carbon is processed by phosphoric acid for bamboo vinegar liquid, dosage of activated carbons 24 mg/ml bamboo vinegar, dosage of activated carbons 10 mg/ml bamboo vinegar liquid and its distillate, adsorption time is 20 min, adsorption temperature is 60 ~C, pH=3.0, in this condition, the color removal rate of phosphoric acid processing hemp activated carbon is up to 85~; The color removal rate of zinc chloride processing hemp activated carbon is up to 60~/~o. The maximum adsorption of phosphoric acid processing hemp activated carbon is up to 358. 3~427.3 mg/g. The conclusion is drawn： The color removal rate and deodorizing rate of phosphoric acid processing activated carbon are higher than other activated carbons for the decolorization and deodorization of bamboo vinegar liquid.
