The dispersion effect of degraded cellulase from Bacillus methlylotrophicus Y37 and the dispersion effect of cellulase and sodium dodecyl sulphate (SDS) together on copper(II) phthalocyanine (CuPc) pigment is studied for the first time in this study. Particle size distribution is used to determine the effect of degradation time for cellulase (1,2,3,4,5,6 and 7 h). Spectral analysis as UV-Vis, fluorescence, and particle size analysis are investigated to find out the degraded degree of the enzyme. For this work, 4 h is found to be the optimum degradation time. The collaborative effect of SDS with degraded cellulase as dispersant on CuPc is also examined. The effect of degraded cellulase-SDS dispersion solution on CuPc suspension is determined by UV-Vis, fluorescence, FT-IR, and TGA analysis. It is concluded that CuPc has better stability as a pigment when the degraded cellulase and SDS are used together as dispersants in this work.
