Ozone chemistry in aqueous solution -Ozone decomposition and stabilisation
Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. Additives can either accelerate the decomposition rate of ozone or have a stabilising effect of the ozone decay. By contro...
متن کاملSonolytic Decomposition of Ozone in Aqueous Solution: Mass Transfer Effects
The sonolytic degradation of ozone (O3) was investigated in both closed and open continuous-flow systems to examine effects of mass transfer on chemical reactivity in the presence of ultrasound. Degradation of O3 followed apparent first-order kinetics at frequencies of both 20 and 500 kHz in all the systems. Degassing of O3 was observed at 20 kHz due to the effects of rectified diffusion and la...
متن کاملThe Decomposition of Cysteine in Aqueous Solution*
In a recent study (1) it was shown that cystine could be decomposed by boiling distilled water with the formation of cysteine, hydrogen sulfide, and elementary sulfur. The decomposition of cysteine under similar conditions should aid in a clearer explanation of the mechanisms involved in the breakdown of these two amino acids. The action of alkaline reagents on cysteine and its derivatives has ...

متن کاملSonolytic decomposition of aqueous bioxalate in the presence of ozone.
Ultrasonic irradiation in the presence of ozone is demonstrated to be effective for the rapid oxidation of oxalic acid, bioxalate, and oxalate (H(2)C(2)O(4)/HC(2)O(4)(-)/C(2)O(4)(2-)) in aqueous solution to CO(2) and H(2)O. The degradation rate of bioxalate exposed to "sonozone" (i.e., simultaneous ultrasonication and ozonolysis) was found to be 16-times faster than predicted by the linear addi...
