摘　　要：通过电子能谱对不浸酸高pH值鞣制的革样进行分析。结果显示,革样中主要的元素为C、N、O,这是构成胶原的主要成分;鞣制1h和4h后,铬和硫周围的化学环境及含量的变化不大,说明不浸酸鞣制时鞣剂的渗透与结合基本完成。通过分析发现,在革中存在Ca2p,中间层相对较多,说明在不浸酸直接鞣制过程中,与胶原结合牢固的钙较难除去。No - pickling chrome tanned leather was analyzed by electron energy spectrum. It shows that the main elements in leather are C, N, O. The chemical circumstance and content of chrome and sulfate in the middle layer are almost the same after tanning for 1 h and 4h, which indicate that the permeation and combination of the tanning agent have finished. There is much Ca2p in the middle layer of the leather, which shows that calcium is hard to remove in the no - pickling chrome tanning process.
