摘　　要：对蛋白酶及氢氧化钠催化水解制革含铬废弃物进行了初步研究。试验结果表明 :酶催化水解时 ,起始p H高 ,革屑水解率大 ,水解液中蛋白质含量高 ,水解产物分子量小 ;碱催化水解时 ,产物分子量较大 ,但水解率低于相同碱量下的酶催化水解的。The subject was to elementarily study on collagen hydrolyzed from chromed leather wastes catalysed by alkali and protease. The results showed that the rate of hydrolysis and content of protein were high when the beginning pH was high, but the molecular weight of the production was low. The molecular weight of the protein was high and the rate of hydrolysis was low when it was catalyzed by alkali.
