用极谱法测定硫氰酸铅络合物的各级稳定常数,结果如次:K1=6.03,K2=9.77,K3=9.27,K4=8.34,K5=7.26,K6=4.30(25℃,用高氯酸纳维持μ=3).又用同法测定硫氰酸锌络合物的各级稳定常数如下:K1=0.724,K2=7.94,K3=15.8,K4=19.5,K5=16.6,K6=4.3(25℃,用高氯酸钠维持μ=3).

The half wave potential of lead and zinc ions were determined at 25℃ in sodium perchlorate-sodium thiocyanate mixtures over the range of 0.10-2.15 M for the lead system and 0.34-2.11 M for the zinc system, both at an ionic strength of 3.0.
