Abstract: The standard of granular activated carbon for decoloration of citric acid was investigated by the method of math statistic. On the basis of considerable experiments, items of granular activated carbons for the decoloration in the production of citric acid were decided. Moreover, the results show that the item of methylene blue adsorption should be recommended to evaluate the decoloring capacity of activated carbons for the production of citric acid, rather than the adsorption capacity of acetic acid.

Key words: granular activated carbon, citric acid, methylene blue adsorption, standard
