Reported is a·cell designed specifically for high speed anodic stripping analysis .. Lead,.for example, is determined at the 1-.ppb level within 10 min and with a precision of 5%. This time _.includes aliquoting, sparging, amalgam accumulation, scanning, and cell cleaning. In operation, the solution is forced into ·a thin film configUration 1-mm thick.by rotating the cell, then spa:rged with nitrogen within 75 sec. The cell is stopped rotating; the solution returns to the floor of the cell; and, the 8.ma.lgam accumulation step is effected within 7 min or less. A high-speed stirrer of new design is employed. A step and hold voltage ramp is used for the stripping scan. The stripping current is digitized directly employing the bipolar digipotentiogrator and the digital data are distributed in time in a pulse height analyzer operated in the multichannel scaling mode. The stored data are transferred onto magnetic tape and are processed with a user interactive.computer program which requires a CDC-6600 computer equipped with a TV-console, a teletype, and light pen accessories. Two methods of purifying KCl supporting electrolytes are offered. One method employs the crystal adsorption:phenomenon. The other uses an aluminum/ mercury amalgam exchange in which electroinactive aluminum ions a:ce,exchanged for trace electroreduc'ible ions. .~· ~i 0 ' . -l~ -.~ 1 (>} .;."f .l'l :J! ~~ .:! ~ \;l .I • ti> Cr·lf ~ . ~
