| Popis: | Aim:Biodegradability is a process for disposition to disintegrate as the result ofnatural processes. The determination of biodegradability would provide someinformation about persistancies for example millions tones of leatherespecially shoes used every year and wasted every year and also would give riseto possibilities utilization of those wastes as by-products. Although leatheris a biological and best comfortable material for human body, as a result oftanning procedure it would become so durable that it’s normal life needs tokeep on. Usage of biocidal in leather production has increased a lot in recentyears. Herein the question is how much durability should necessarily beexecuted and should the durability turn to persistency during usage of biocide.From this viewpoint biodegradability is to assess tanning quality and effect ofbiocide, enough or far beyond, and to evaluate its lifecycle in theenvironment, easily decomposable or traceble for many years. Methods:Biodegradability tests, as a reference being developed for leathers, is basedon the determination of generated CO2 titrimetrically. In this study, inaddition to the generation rates of CO2 assessed by titration of leathersamples with and without commercial biocides prepared according to ISO/DIS20136 final draft standard biodegradability were attributed to DHAmeasurements. Results: DHA test one of the fastest and reliable standard methodfor determination of total metabolic activity were compared by effect ofbiocides used leather tanning on its biodegrability. Conclusion: In conclusionthis study proved that DHA measurements for the biodegradibility observationsis appropriate as compared to the biodegradability tests based on the rates ofCO2 occurrences. Keywords: Biocide, biodegradability, leather, CO2, DHAmeasurement |
