Adsorbent for phosphorus and method for production of adsorbent for phosphorus |
摘要 |
An amorphous substance obtained by mixing volcanic ash with or without added clay and water and, if necessary, a surfactant, kneading the mixture, and shaping and firing. Additives such as camphor or naphthalene may be included prior to firing for plasticity and to form pores. The resultant mixture possesses an ability to adsorb phosphorus selectively. When this substance is placed in contact with a phosphorus-containing liquid, it removes phosphorus from the liquid.
