| Abstract: | Objective: dsorption of tea residue on purification technology of bamboo vinegar.Methods: The effect of 3 refining technics on p roperties of crude bamboo vinegarwas tested.Result: The results showed thatthe distillation,asorption of tea residue and activated carbon adsorp tion allmade the index of the absorbency,acidity,soluble tar and refractivity be lower than the crude bamboo vinegar,and the refining technics of thedistillation,decomp ression distillation and rectification decreased the value of pH,but activated carbon adsorp tion increased the value of pH.Conclusion: dstillation is best,adsorption of tea residue between distillation and carbon adsorption |
