摘要： A process control system for metal depositing baths for monitoring the chemical composition of a bath liquid provides that, in the event of a deviation of a component of the bath liquid from a reference value, the bath liquid is regenerated by supplying correcting liquid to the bath. The system includes an automatically operating analyzer which is connected to a measured value adjusting device which, in dependence upon the difference established between a reference value and an actual value of the bath liquid component subject to analysis, controls the supply of the correcting liquid to the bath. A common process control system for a plurality of galvanic baths includes a main programmer, a bath selection programmer and analysis programmers which can be selectively connected by the selection programmer, and which in accordance with the individual components of the bath liquid which is to be analyzed, actuate specific analyzer sections of the analyzer where each measured value adjusting device which is connected to an analyzer section will, in the case of a difference in measured value, control the supply of the correct quantity of the specific correcting liquid to the particular bath which is subject to analysis.

摘要： An analysis system for determining total copper content in waste-water, as from a galvanizing system, comprises periodically taking samples from such waste-water, acidifying such samples with a metalliferous acid containing a metal which forms a strong cyanogen complex and which exhibits a larger electro-negative potential than copper, such as Pd, reducing cupric ions to cuprous ions, adjusting the pH of the resulting sample solution, adding a copper color-forming reagent, such as bathocuprione disulfonic acid salt, and determining the color content by colorimetry. In order to determine a reagent value, a prepared waste-water sample can be subjected to colorimetry before and after addition of the color-forming reagent.

摘要： A method for the automatic, electro-chemical determination of the end point of titration utilizing an initial, continuous addition of the titrant, up to a predetermined value, followed by a step-by-step addition with a resting time inserted therebetween for stabilization of the solution is disclosed. As the titrant is being added to the bath sample in constant volume units, a measured value is formed after every such addition. The difference to the preceding measurement is determined and the three consecutive differences of greatest magnitude are utilized in a mathematical formula for calculating the end point. The titration ceases when the greatest difference lies between two lesser values.

摘要： An automated analysis process and apparatus for analyzing the amount of dispersed water-immiscible solid organic substances in sewage water whereby a precise sample of sewage is taken from a sewage source, admixed with various reagent solutions, including a K.sub.2 Cr.sub.2 O.sub.7 --solution under heat-time conditions so that a reaction occurs between the sewage and the reagent and all of the organic substance in the sample are oxidized while simultaneously at least some Cr.sup.+6 --ions are reduced to Cr.sup.+3 --ions. During this oxidation-reduction reaction and at a location remote therefrom, a precise amount of Fe.sup.+2 --ions is generated within an aqueous acidic Fe.sup.+3 --ion containing solution via a coulometric reduction process. Thereafter, the reacted sewage-reagent solution is admixed and reacted with the so-generated Fe.sup.+2, Fe.sup.+3 --ion containing solution so that any residual Cr.sup.+6 --ions in the sewage-reagent solution are reduced to Cr.sup.+3 --ions and at least some Fe.sup.+2 --ions remain. By biamperometrically titrating the resultant Fe.sup.+2 --ion containing solution with a standardized Cr.sup.+6 -- ion containing solution, the precise amount of Fe.sup.+2 --ions within the titrated solution is determined and this provides an indirect indication of the amount of organic substances within the sewage sample. Pneumatic, hydraulic and electrical circuits actuate the various steps and are themselves actuated and controlled by a master control means, such as preprogrammed computer means, which also computationally integrates data from the overall process and automatically determines the amount of organic substances in the samples under analysis.

摘要： A method for determining current efficiency in a galvanic bath employs a measuring cell within which a sample is introduced from the galvanic bath. In this sample, onto a preferably rotating electrode metal is precipitated. A negative voltage is applied at constant current during a first predetermined time during the precipitating. Thereafter, the precipitated layer is anodically eroded by use of a suitable electrolyte solution upon pole-reversal of the DC voltage. The current efficiency is then calculated.
