The removal of colored-toxic materials from industrial wastewater has been subject to investigations since years. There are more than several methods to overcome these problems. In this article, sodium sulfite as a scavenger was used to remove the color of basic red 46 and methylene blue in solution as model pollutant materials in water. Color removal kinetics was studied by using sodium sulfite amount, pH of the solution, time and temperature as parameters. The effect of these parameters was reported according to the decay kinetics of absorbance of the dye compounds in solution by using molecular absorption spectroscopy. It observed that the color degradation of basic red 46 obeys bi-exponential decay whereas methylene blue obeys single exponential decay. The kinetic rate constants were determined from fit of the absorbance decay studies and temperature dependence of process was discussed with Arrhenius equation.

Endüstriyel atık sulardan renkli zararlı maddelerin giderilmesi yıllardan beridir incelenmektedir. Bu problemin üstesinden gelmek için birçok metot bulunmaktadır. Bu makalede, model kirletici olan bazik kırmızı 46 ve metilen mavisinin sulu çözeltisinin renk giderilmesinde sodyum sülfit kullanıldı. Renk giderim kinetiği, sodyum sülfit miktarı, çözelti pH’sı, zaman ve sıcaklık parametreleri üzerinden incelendi. Bu parametrelerin etkisi moleküler absorpsiyon spektroskopisi kullanılarak boyar maddelerin absorbans durulma kinetiği şeklinde rapor edildi. Bazik kırmızı 46’in durulma kinetiği iki üstel bir durulma gösterirken metilen mavisinin durulma kinetiği tek üstel olarak gerçekleşmiştir. Absorbans durulma çalışmalarından kinetik hız sabitleri hesaplandı ve proseslerin sıcaklığa bağımlılığı Arrhenius denklemiyle tartışıldı.
