Study Progress on Dechroming and Extracting Collagen from Chrome Shavings
Abstract:The main components of chrome leather shavings were collagen and chromium, therefore it had greater value of resource utilization. A great deal of work had been done on the resource utilization of chrome leather shavings at home and abroad. The technology of dechroming and extracting collagen from chrome leather shavings had been proposed,such as oxidation,hydrolysis and combination methods. In order to realize resource utilization of chrome leather shavings and promote the ecological and sustainable development of leather industry. In this paper, the dechroming rate and collagen extraction rate were use as main evaluation indexes, the technologies of resource utilization of chrome leather shavings were introduced briefly, and the characteristics, advantages and disadvantages of these technologies were analyzed. The combination method was put forward as the best method for dechroming and extracting collagen from chrome leather shavings, and the prospect of resource utilization of chrome leather shavings was prospected.
Keywords: chrome leather shavings dechroming collagen dechroming rate collagen extraction rate
