Bactericidal allophanic materials prepared from allophane soil II. Bactericidal activities of silver/phosphorus-silver-loaded Allophanic specimens

摘要

Bactericidal activities against Escherichia coli and Staphylococcus aureus in water for two sterilizing allophanic specimens prepared by loading silver or phosphorus along with silver on an allophane soil carrier, were examined in comparison to those of silver-loaded zeolite specimens. The sterilizing allophanic specimens were added to bacteria suspensions (1 × 10~6×10~7 cells of E. coli or S. Aureus/1 cm~3 of suspension) and stirred for a fixed period.
