将制革工业中的废弃皮革经过非织造工艺制成废鞣革胶原水刺布，通过戊二醛交联将单宁固化到废鞣革胶原水刺布上。首先研究单宁固化废鞣革胶原水刺布的形态结构及强伸性变化，然后分别研究Pb2＋的初始浓度、溶液温度、溶液pH值对Pb2＋吸附量的影响。结果表明：随着Pb2＋的初始浓度、溶液温度、溶液pH值的增大，Pb2＋的吸附量逐渐增大，最大为25．95 mg/g。最后利用0．1 mol/L稀HCl溶液对吸附材料进行解吸附试验，并讨论单宁固化废鞣革胶原水刺布吸附材料的解吸附性能及再生性。
將製革工業中的廢棄皮革經過非織造工藝製成廢鞣革膠原水刺佈，通過戊二醛交聯將單寧固化到廢鞣革膠原水刺佈上。首先研究單寧固化廢鞣革膠原水刺佈的形態結構及彊伸性變化，然後分彆研究Pb2＋的初始濃度、溶液溫度、溶液pH值對Pb2＋吸附量的影響。結果錶明：隨著Pb2＋的初始濃度、溶液溫度、溶液pH值的增大，Pb2＋的吸附量逐漸增大，最大為25．95 mg/g。最後利用0．1 mol/L稀HCl溶液對吸附材料進行解吸附試驗，併討論單寧固化廢鞣革膠原水刺佈吸附材料的解吸附性能及再生性。

The waste leather was made into waste collagen fiber spun-lace fabric by textile manufacturing process. This kind of spun-lace fabric was then immobilized by tannin through the cross-link of glutaraldehyde. The structure and strength of the fabric were studied.Then the influences of initial Pb2+concentration, the temperature and pH value of the solution on the absorption of Pb2+have been studied.It shows that with the increase of these three parameters, adsorption of Pb2+increases,up to 25.95 mg/g.Finally, the fabric that has absorbed Pb2+was treated by 0.1 mol/L HCl solution to study its properties of de-sorption and performance of recycling.
