| Abstract: | The topic used chrome shavings as raw materials, through the acid and acid-base composite dechroming experiments, and by selecting the appropriate process conditions, to obtain the collagen sample with lower chromium content. With the hydrolysis rate and chromium content as indicators, the effect of pretreatment, raw material amount, reaction time and reaction temperature on dechroming was examined systematically, and dechroming conditions were optimized by orthogonal test. |
