ON THE DISINFECTION OF ANTHRAX-SPORES WITH CHLORIDE OF LIME

Abstract

The disinfecting action of chloride of lime has already been confirmed by many authors, though its practical application was chiefly limitted to the purification of water. The reason of its narrow use in practice was thought to lie in its defective properties that quantity of available chlorine is not constant, and that free chlorine is easily consumed by oxidizable substances contained in infected materials. Recently, however, the application of chloride of lime is becoming wider, being used for the disinfection of fruits, vegetables, excreta, infected bath water and sewage. The present author thinking very desirable to get clearer insight to the nature of disinfection with chloride of lime, conducted the following experiment with the aim of increasing its disinfecting power and of reducing the consumption of free chlorine by oxidizable substances. The essentials of the results obtained are presented as follows. Relation between free chlorine contained in the solution of chloride of lime and its disinfecting power. Although chlorine does not exist in the solution of chloride of lime prepared with distilled water, except Cl' and ClO' yet its well-water solution may probably contain free chlorine in a small quantity. Having prepared the solution with well-water, I have estimated the chlorine content and tested its disinfecting power.
