WEATHERED HERMATYPIC CORAL MATERIAL |
摘要 |
Weathered reef-building coral is immersed in an aqueous alkali solution under reduced pressure to carry out alkali washing to make the aqueous alkali solution penetrate into the weathered reef-building coral throughout its fine structure inside the porous tissue, which is subsequently washed with water until a washing from the inside of the porous tissue is neutralized. As a result of this washing, various marine algae, various microorganisms including Vibrio bacteria inhabiting the ocean and other various organic substances held in the inner fine structure of weathered reef-building coral can be removed. Thus, a weathered reef-building coral material can be obtained whose safety has been ensured. This weathered reef-building coral material is suitable for food materials, filter mediums for water purifiers and so forth. <IMAGE> |
