BÖLÜM V: SONUÇLAR
Sonuç olarak, bu çalışma için özel olarak hazırlanan NFC-doplu TiO2 fotokatalist özellikle evsel ve ardından da endüstriyel atıksulardan antibiyotik gideriminde oldukça başarılı sonuçlar ortaya koymuştur. Bu çalışmalardan yola çıkılarak özel fotoreaktörler tasarlanmasıyla NFC-doplu TiO2 fotokatalitik oksidasyon prosesleri konvansiyonel sistemlerle sağlanamayan antibiyotik gideriminde alternatif arıtma yöntemi olarak kullanılabilir.
