1. 20 speciemens of asbestos are examined about their properties as the filter aid.
2. Although they contain 0.003 to 6.210 % of iron soluble in N-HCl, the iron dissolved in - the Japanese sake is only 0.002 to 0.012 %.
3. As the quantity of asbestos to be used for filtering is very small as compared with the quantity of the liquid to be filtered, it seems that the iron content of asbestos is of no great importance.
4. The velocity of filteration can be compared under certain conditions. There are various types of filteration time as shown in the table.
5. Through our examinations, No.12 or 13 is the best among all the speciemens. Both of them are the products from Arizona and they had been treated with. hydrychloric acid or water.
