南九州産白色粘土の研究 : 第9報 吉野山粘土の活性化 STUDIES OF THE WHICH CLAY IN THE SOUTH KYUSHU : REPORT 9. ACTIVATION OF THE YOSHINOYAMA CLAY 小牧, 高志 KOMAKI, Takashi open access Generally，clay that the chief ingredient of montmorillonite is useful in various way，and especially is in useful for the purification of petroleum and decoloring agent. The Yoshinoyama clay is montmorillonite as its main substance which is rarely found in the South Kyushu． The author studied the activation of this clay by the change of concentration of sulfuric acid，volume and reacted time，in concequent of this study，the relation of the activation and the reacted time and adsorption of coloring matter is parallel，but the other hand，it is very interesting that the specific surface area is maximum at 0.360 activated percentage and at over activation the area shows a decline and proved it was used as the active clay by this study. 鹿児島大学 Kagoshima University 1962-09 jpn departmental bulletin paper VoR http://hdl.handle.net/10232/10673 https://ir.kagoshima-u.ac.jp/records/7568 0451212X AN00040363 鹿児島大学工学部研究報告 The research reports of the Faculty of Engineering, Kagoshima University 2 161 167 https://ir.kagoshima-u.ac.jp/record/7568/files/AN00040363_v2_p161-167.pdf application/pdf 2.5 MB 2016-10-28 1962-09
