Polymer Degradation and Stability | 2003

Solvent effects on the lipase catalyzed biodegradation of poly (ε-caprolactone) in solution

G. Sivalingam; Sujay Chattopadhyay; Giridhar Madras

BET surface area was prepared by solution combustion method and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and BET surface area. This catalyst was used for the photocatalytic degradation of various dyes such as heteropolyaromatic dye (Methylene blue), anthraquinonic dye (Alizarin S), and azoic dyes (Methyl red, Congo red, and Orange G). The effect of catalyst loading, initial concentrations of the dyes, pH, and transition metal doping on
