摘　　要：本文采用非间隔流动分析技术，建立了一种在线测定硫酸锌溶液中痕量锗的方法。显色体系为ＨＣｌ－水杨基荧光酮－乳化剂ＯＰ，并用多波长光度法克服了试样中高浓度硫酸锌以及背景吸收的影响。采样频率３０样／ｈ，测定范围１０～１００μｇ／Ｌ。该方法已用于锌冶炼厂净化过程中痕量锗的在线分析。method for on-line analysis of germa-nium in the range of 10～100ppb in zinc sul-phate solutions based on unsegmented-flowanalysis techniques with a sampling frequen-cy of 30 samples/h is described.The colori-metric system employed is Ge-salicylfluo-rone ( SAF )-p-octyl polyethylene glycolphenyl ether(OP) with 1mol/L HCl acidity. Multiwavelength absorbance measurementsare employed to compensate for the interfer-ence of the highly concentrated zinc sulphate(as high as 160g Zn/L)and sample turbidi-ty,The method developed has been appliedto the determination of trace germanium inthe purification process at a zinc smelter.
