Abstract
At least part of the effluent from an ion exchanger flows past a first and second electrode. The electrodes are mounted within the pipe carrying the fluid so that they are visible from the outside. A DC voltage is applied between the electrodes. If the effluent contains a metal which should have been adsorbed by the ion exchanger, its presence is indicated either by a change in the voltage-current curve of the electrodes or a change in color of the cathode. Either a single metal or a group of metals may be precipitated.
Claims9
In a system comprising ion exchanging means and a stream of liquid comprising ions of at least one specified metal flowing in a predetermined direction through said ion exchanging means, apparatus for furnishing an indication of the complete loading of state of saturation of said ion exchanging means with respect to said specific metal, comprising
- a first and second electrode positioned in said liquid following said ion exchanging means in said predetermined direction;
- and
- means connected to said electrodes for creating therebetween a predetermined potential differnce so that said specified metal when not retained in said ion exchanging means forms a deposit on one of said electrodes.
