Abstrakt: | This work focuses on the influence of cross-linking with higher-molecular glycol diepoxides (and glycerol triglycidyleter) on biologic anaerobic degradation of protein hydrolysate (trade name Hykol) produced from chrome-tanned wastes (shavings). Samples of Hykol cross-linked with selected higher-molecular diepoxides were degraded with anaerobic sludge from a municipal plant at temperature 35o C. Biodegradation of tested modified hydrolysate samples produced recorded quantities of biogas (CH4, CO2). Attention was also given to preparation, the determination of solubility, intrinsic viscosity and IR spectra of prepared samples. In comparision with Hykol the degree of degradation decreased approx. from 70-50%. | ||||||||||
