摘　　要：研制了一种球形镍金基体真空镀汞膜电极。采用2．5次微分极语法对电极性能进行了考查，在0.1MKCl中，镉的线性范围为4×10^(－8)－6×10^(－11)M，证明该电极性能稳定，灵敏度高，重视性好。A spherical electrode with mereury film vacuum-plated on nicdel-gold substrate was prepared and its performance was tested by differential polarography The linear range of Cd2+ in 0.1 M KCl is 4 .10 ×10^(-8)- 6 × 10^(-11) M. The performantce of the elec- trode is stable and theesnsitivity is 2×10^(11) with good reproducibility.
