Abstract

The rules of ozone generation produced by yellow phosphorus and oxygen were carried out by single-factor experiments in this article. The results showed that with fixed yellow phosphorus concentration (2 g L-1) and oxygen volume percentage (10 %), the rate of ozone net generation reaches a maximum of 1.44×10-4 g L-1 min-1 at initial stage when reaction temperature, stirring speed, and flow rate reach 50 , 800 r min-1 and 600 mL min-1 respectively. There is a clear linear relationship between the total concentration of ozone net generation and the initial concentration of yellow phosphorus, which is :=1:2 in experimental conditions. The total concentration of ozone generation is reduced by increasing temperature or stirring speed, but increased by raising oxygen concentration. Adding limestone may lead to the decrease of both the rate and total quality of ozone production. The pH value of this reaction system can rapidly reach a stable state, which can be well utilized to the separation and recovery of phosphorus.
