摘　　要：文章研究了有机酸N缓冲体系以及助剂CNFC对Fe2+预媒处理紫绒的作用。研究证明,助剂CNFC与Fe2+络合生成CNFC-Fe2+。有机酸N与Fe2+有一定的结合,并能缓慢释放出Fe2+。相对于无机酸以及乙酸-乙酸钠,有机酸N缓冲体系更有利于紫绒对Fe2+的吸附;无论在乙酸-乙酸钠或有机酸N中,助剂CNFC对紫绒吸附Fe2+均有作用,但助剂CNFC更有利于Fe2+对紫绒的定向吸附,同时助剂CNFC对紫绒上吸附Fe2+有明显的助脱作用,有利于残留Fe2+的去除。得出初步的预处理条件为:浴比1∶50,紫绒0.5 g,FeSO4 0.03 mmol,CNFC(质量浓度10 g/L)2 mL,25℃,pH值5.0,120 min。In this paper,the influences of buffer system and agent CNFC on Fe2＋ pre-treatment for colored cashmere were studied.It was concluded that CNFC-Fe（Ⅱ）was obtained by the complexation of agent CNFC and Fe2＋,and the organic acid N was capable of capture or release Fe2＋.Comparing with inorganic acid or NaOAc～HOAc,organic acid N buffer system was helpful to the absorption of Fe2＋ on colored cashmere.Under the condition of organic acid N,agent CNFC was able to affect the oriented absorption of Fe2＋ and the removal of residual iron.The recommended pretreatment condition was as follow：bath ratio 1：50,cashmere 0.5 g,FeSO4 0.03 mmol,agent CNFC 0.8 g /L,pH value 5.0,25 ℃,120 min.
