Current-time characteristics of the rapidly dropping mercury electrode

Polarographic Theory, Instrumentation, and Methodology

“…The effects were observed with thallium and silver. Tamamushi, Momiyama, and Tanaka (229) made current-time studies with the rapidly dropping electrode, finding the limiting current to be controlled both by diffusion and convection in potential ranges where the mercury surface was in motion.…”

“…Lockwood (125) has described a device for synchronizing two dropping mercury electrodes through detachment of the drops by a solenoid action. Tamamushi, Momiyama, and Tanaka (229) have done further studies on the characteristics of the rapidly dropping electrode and have recommended it for use in flowing systems, the current being relatively insensitive to flow in the solution.…”

Cell for continuous analysis in flowing solutions with the rapidly dropping mercury electrode

“…In the last decades, there have been several polarographic approaches to the problem of continuous analysis in flowing solutions (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). For this purpose, both the conventional dropping mercury electrode (DME) (2-8, 11, 12, 14, 15) and the rapidly dropping mercury electrode (RDME) (9,10,13) have been used. The RDME differs from the DME in the shorter dropping time (t = 1.5-0.1 sec).…”

“…The RDME differs from the DME in the shorter dropping time (t = 1.5-0.1 sec). It can be obtained with L-shaped capillaries (16), horizontally placed capillaries (9), or large bore capillaries (10). In conjunction with the use of DME and RDME as detectors in flowing solutions, special cells have been developed (2,3,(5)(6)(7)(8)10,12,13).…”
