GARCES GIRALDO, Luis Fernando. Analysis of the optimal conditions for the mineralization and degradation of Novactive Red F6BS in waste water. Rev. P+L [online]. 2012, vol.7, n.1, pp.80-87. ISSN 1909-0455.

Introduction. The research work consisted of an analysis of the conditions to treat waste waters with Novactive Red F6BS dye by the use of advanced oxidation processes with artificial light to eliminate persisting substances from the water. Objective. To evaluate the optimal conditions to remove the Novactive Red F6BS dye in waste waters by the use of an artificial light source. Materials and methods. A MIGTHY PURE 60 Hz ultraviolet light lamp was used with a glass bucket that stores 15 liters of sample. This sample was re-circulated with a pump with a 0.047 L/s flow. Results. The best results for the Novactive Red F6BS dye were 76.2% of degradation and 49.4% of mineralization in two hours, with the E7 test (60 mg/L of FeCl₃ and 1 mL/L of H₂O₂) . Conclusions. The dye is faster degraded and mineralized with the FeCl₃; this took place in the E7 test (60 mg/L of FeCl₃ and 1 mL/L of H₂O₂).
