摘　　要：本文使用NaOH与CaO两种碱对废弃含铬革屑进行水解制备胶原蛋白粉,通过探究改变单一碱用量,以及两种碱的不同用量配比对蛋白粉产品水分、灰分、铬含量、氮含量等性能的影响,综合各项指标得出:使用单一碱进行水解时,CaO与NaOH的最佳用量均为8%;改变两种碱用量配比时,CaO与NaOH的最佳用量比为5∶3。In this paper,NaOH and CaO were used to hydrolyze the waste chrome shavings to prepare collagen powder,and the effects of changing the amount of single base and the different ratios of the two bases on the moisture,ash,chromium content and nitrogen content of the protein powder product were investigated.According to various indicators,the optimum dosage of CaO and NaOH is 8%when using a single base for hydrolysis.When the ratio of the two bases is changed,the optimumratio of CaO to NaOHis 5∶3.
