This paper summarized the characters and acting principles as well as the application of low temperature plasma technology on the surface modification of protein biomaterials, and forecasted their applied prospects. Especially it make mention of improved absorption and combination of chrome in leather processing by low temperature plasma on the surface modification of collagen fibrils, that it may come into being a new technology of free-chrome.

概述了低温等离子体的特点和作用原理，并总结了低温等离子体技术在蛋白类生物材料表面改性中应用，展望了该技术的应用前景，特别指出了通过低温等离子体对皮胶原纤维的改性处理，有望提高铬的吸收与结合，甚至实现无铬鞣制新技术，这将对传统铬鞣工艺产生重要作用。

Using H2SO4 as acidulant,chromic sulfate with high purity was obtained by crystallization,which was applied to leather industry as chrome tanning agent .

将电镀废水中的六价铬还原成Cr，用化学沉淀法和絮凝法将其转化为Cr3沉淀，通过硫酸酸化，结晶为高纯硫酸铬，作为皮革工业的铬鞣剂。

We find good ways to hydrolyze and modify by experiments. Through the experiment, good tanning, retanning and filling properties, as well as, better chrome exhaustion are found in the modified products, with the help of selecting suitable ways to hydrolyze and modify the chrome shavings. The crust leather is possessed of fullness, softness, good dyestuff...

通过实验研究，选择适宜的水解铬革屑的方法和改性条件，发现改性产品在应用中具有较好的鞣制复鞣填充作用，可促进对铬的吸收，坯革丰满、柔软、有弹性，粒纹清晰细致；对染料吸收性好、着色均匀；并可提高成革的收缩温度，降低废液中的含铬量

In two-stage chrome tanning process,the chrome absorptivity can be increased from 86.80%to 99.09%,and the chrome fixation can be increased from 76.07%to 90.21%by the same treatment.

由于胶原对铬的吸收率和固定率的提高，常规铬鞣时可将标准铬粉的用量由传统的6%减少到4%，。

Because of the enhancement in chromium absorptivity and fixation,the dosage of normal chrome powder can be reduced from 6%to 4%in conventional process,and can be reduced from 6%to 3%in two-stage chrome tanning process,and thus the chrome absorptivity and fixation can be enhanced further.

两步铬鞣时可将标准铬粉的用量由传统的6%减少到3%，这时铬的吸收率和固定率还会进一步提高。
