摘　　要：通过对比两性改性的改性剂、改性温度、改性pH,磺化改性的磺化时间、磺化温度对荆树皮栲胶进行两性及磺化改性,得出了较优的改性路线,进行了其对皮革中Cr6+的预防作用的应用试验。研究结果表明:荆树皮经过两性改性和磺化改性后,应用在皮革复鞣中,对蓝湿革颜色无影响,并对皮革中的Cr6+具有较好的预防作用。In the amphoteric and sulphuric modification of black wattle extract, the comparison of modification agents, temperature, pH of amphoteric modification, as well as sulphuric modification time and temperature was carried out. The optimal way of synthesization was obtained. And the applied experiment in leather to control the hexavalent chromium was also carried out. The results show that the modified product could well control hexavalent chromium in crust and has no bad effect on the color of green leather after retanning.
