极谱法测定痕量碲已有不少文献发表,但在盐酸-结晶紫底液中,用示波极谱测定痕量碲的工作还未见有报道。我们发现,在盐酸-结晶紫底液中,碲有一清晰而又灵敏的导数波,峰电位约-0.9V(vs SCE),碲浓度在2.4—80ppb范围内与峰高成正比,碲浓度在80ppb—1ppm范围内与峰高的平方根成反 Polarographic determination of trace tellurium has been published in many papers, but in hydrochloric acid - crystal violet solution, the use of oscillopolarographic determination of trace tellurium has not been reported. We found that tellurium has a clear and sensitive derivative wave in hydrochloric acid-crystal violet base solution with a peak potential of about -0.9V (vs SCE), a tellurium concentration in the range of 2.4-80 ppb proportional to peak height, a tellurium concentration in the range of The inverse square root of the peak height is in the range of 80 ppb to 1 ppm
