目的：研究废弃茶叶渣对竹醋液吸附脱色提纯工艺。方法：探讨了分别用蒸馏、茶叶渣吸附、活性炭吸附对竹醋液吸光度及其他物理性质的影响。结果：蒸馏、茶叶渣吸附、活性炭吸附后竹醋液的最大吸光度0．117，1．613，1．896。结论：蒸馏脱色、脱臭效果最好，其次是活性炭，茶叶渣吸附效果一般。
目的：研究廢棄茶葉渣對竹醋液吸附脫色提純工藝。方法：探討瞭分彆用蒸餾、茶葉渣吸附、活性炭吸附對竹醋液吸光度及其他物理性質的影響。結果：蒸餾、茶葉渣吸附、活性炭吸附後竹醋液的最大吸光度0．117，1．613，1．896。結論：蒸餾脫色、脫臭效果最好，其次是活性炭，茶葉渣吸附效果一般。
목적：연구폐기다협사대죽작액흡부탈색제순공예。방법：탐토료분별용증류、다협사흡부、활성탄흡부대죽작액흡광도급기타물이성질적영향。결과：증류、다협사흡부、활성탄흡부후죽작액적최대흡광도0．117，1．613，1．896。결론：증류탈색、탈취효과최호，기차시활성탄，다협사흡부효과일반。
Objective： dsorption of tea residue on purification technology of bamboo vinegar. Methods： The effect of 3 refining technics on properties of crude bamboo vinegarwas tested. Result： The results showed thatthe distillation, asorption of tea residue and activated carbon adsorption allmade the index of the absorbency, acidity, soluble tar and refractivity be lower than the crude bamboo vinegar, and the refining technics of thedistillation, decompression distillation and rectification decreased the value of pH, but activated carbon adsorption increased the value of pH. Conclusion： dstillation is best, adsorption of tea residue between distillation and carbon adsorption
