Abstract

Naphthol Green B (NGB) is a synthetic azo dye widely used in various industries, including textiles and leathers. NGB poses significant environmental and ecological concerns when released into natural water systems. This paper investi- gates the decolorization of NGB using UV/sulfite system. The % decolorization of NGB was optimized using 32 Full Factorial Design (FFD), and the ANOVA results show that the model has a good fit for the data (R2 = 99.54 %, R2 (adj) = 98.76 %) and the significant factors contributing to the % decoloriza- tion are A, B, A2, and B2 where A = mM sulfite and B = pH. The model predicted ≥100 % decolorization with the opti- mum conditions 12 mM sulfite and pH 10. An actual ex- periment was conducted to verify the response, resulting in 96.2 % decolorization which is in good agreement with the model.
