摘　　要：在PVA124－TritonX－100协同作用HAc-NaAc缓冲体系（pH6.5）中，Ag+与邻菲罗林-溴邻笨三酚红形成2：4：1紫红色三元络合物，其λmax=620nm，ε620＝7.0×104,Ag+浓度在0~14μg／25ml内遵循比耳定律。方法用于漂定液中微量银的测定，结果满意。With PVA124-TritoX-100 synergism in HAc-NaAc buffer system (PH=6. 5 ), Ag +and ortho-plenanthroline-bromine ortho-hydroxyquinol react to 2 : 4: 1 purplish red ternary complex compound withλmax = 620 nm,ε620= 7. 0 ×104. Ag+ concentration within 0-14μg/25ml is correspond with Beer's Law. This method is used to determinne the trace Ag in solution.
