First Time

For the first time in Sri Lanka, an attempt was made to measure the outdoor radon levels using CR 39 type passive radon detectors. Preliminary results indicate that in Sri Lanka, 220Rn isotope is more abundance than 222Rn isotope. These results were also confirmed by in-situ measurements. Sri Lanka has one of the highest 220Rn values in the region. It was also noted that environmental conditions and other physical factors have a significant effect on the outdoor radon measurements using passive discriminative detectors.

AbstractThe Electro-Fenton is one of the processes based on the Fenton reaction, which have been investigated to improve the efficiency of classical Fenton treatment. The Electro-Fenton has been shown to be efficient in the degradation of many organic compounds. However, generally there is no true estimation of its efficiency compared to that of the classical Fenton process. This study aimed to compare the two processes using an experimental approach and modelling. First of all, degradation of hydrogen peroxide (externally applied) was studied. It was shown that the Electro-Fenton process needs smaller quantities of iron (5 times less) than the Fenton to decompose the same quantity of hydrogen peroxide. The Electro-Fenton process may also produce hydrogen peroxide in situ (oxygen reduction). This leads to an important reduction in the consumption of chemicals (hydrogen peroxide, small quantities of iron salt). Finally, a study of the degradation of phenol, when hydrogen peroxide was electrogenerated has shown the greater efficiency of Electro-Fenton compared to the Fenton process.
