摘要
本文采用交流示波滴定二次微分技术(d^2E/dt^2～E)发现了5种新的碱性范围内的示波中和滴定指示剂。在水溶液中直接滴定了有机弱酸及有机弱碱的盐类药物。
Five new indicators for oscillopolarographic titration of very weak acids (or kases) and its salts are given. d^2E/dt^2-E curves are used. Compared with (dE/dt)-E curves, the end- point observed becomes sharper. These indicators have keen used in determination of drugs.
