报道了N,N-二仲辛基乙酰胺(简称N_(503))萃淋树脂的合成方法,用AAS法测定了该树脂对金的吸附速率和等温吸附线,在动态试验的基础上,确定了N_(503)萃淋树脂分离、AAS法测定矿样中微量金的方法。
The synthesis method of N, N-diphenylacetamide (N_ (503)) extraction resin was reported. The adsorption rate and adsorption isotherm of gold on this resin were determined by AAS method. On the basis of dynamic test, The method of separation of N_ (503) extraction resin and determination of trace gold in AAS method was established.
