Bakteri Gideriminde Sonofotokatalitik Yöntemin Kullanımı

Bu çalışmada, atık suların mikroorganizmalardan arıtımı için alternatif olan ve son zamanlarda dikkat çekenyöntemler kullanılmıştır. Bu amaçla özellikle atık sularda yer alan Salmonella typhi RSHMB 96051 bakterisiningiderimi sonoliz, fotokataliz ve sonofotokataliz yöntemleri kullanılarak incelenmiştir. Yapılan denemelerde farklıışık şiddetlerinin bakteri giderimindeki etkileri bu prosesler üzerinde çalışılmıştır. Denemelerde ultrases enerjisi veultraviyole ışınlar hem ayrı ayrı hem de eşzamanlı olarak birlikte kullanımlarıyla yapılmıştır. Bu prosesler sırasıylasonoliz, fotokataliz ve sonofotokataliz prosesleridir. Elde edilen sonuçlar karşılaştırıldığında her üç tekniğin debakteri gideriminde oldukça etkili olduğu ancak fotokataliz ve sonolizin birlikte kullanılmasıyla olan etkinin enfazla olduğu tespit edilmiş ve bu yöntemle %100 giderime yaklaşık 6 dakika gibi kısa bir sürede ulaşıldığı tayinedilmiştir.

The Usage of Sonophotocatalytic Process for the Disinfection of Bacteria

In this study, some of the alternative methods have been utilized for the disinfection ofmicroorganisms in the waste water. The disinfection of Salmonella typhi RSHMB 96051 bacteria in the waste waterwas investigated using the sonolysis, photocatalysis and sonophotocatalysis processes. In experiments, the effectsof different light intentities have been investigated with the processes mentioned above. The ultrasound energy andultraviolet light were used seperately and together as well. These processes are called sonolysis, photocatalysis andsonophotocatalysis respectively. The results yielded that all the processes were quite effective. The simultaneoususe of sonolysis and photocatalysis yielded the best results. 100% disinfection ratio was obtained within 6 minutesin this study
