Abstract

During the development of a film (4) passing through a developer bath (1), a fixer bath (2) and a bath for the rinsing liquid (3), it is unavoidable that a film carries silver ions into the bath for the rinsing liquid. The silver ion concentration in the bath for the rinsing liquid is measured e.g. by conductivity using electrodes (4) and (5) and the bath containing the rinsing liquid is exchanged when the concentration of heavy metals exceeds a predetermined value. As a result the developer system can be used in locations without faucets and sewerage for the rinsing liquid. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Messen der Schwermetallkonzentration während der Entwicklung eines Films, der durch ein Entwicklerbad, ein Fixierbad und ein Spülbad geführt wird.The invention relates to a method for measuring the Heavy metal concentration during the development of a Films made by a developer bath, a fixing bath and a rinsing bath is performed.

Die DE-OS 25 17 423 beschreibt ein Verfahren zum Messen der Schwermetallkonzentration im Entwicklerbad um eine gewünschte Konzentration dieser Schwermetalle aufrecht­ zuerhalten.DE-OS 25 17 423 describes a method for measuring the heavy metal concentration in the developer bath by one desired concentration of these heavy metals to obtain.

Gemäß der Erfindung wird die Schwermetallkonzentration im Spülbad gemessen und das Bad mit der Spülflüssigkeit ausgetauscht, sobald die Schwermetallkonzentration darin einen bestimmten Grenzwert überschritten hat. Damit wird berücksichtigt, daß Schwermetalle möglicherweise in das Spülbad überführt werden.According to the invention, the heavy metal concentration measured in the rinsing bath and the bath with the rinsing liquid exchanged as soon as the heavy metal concentration in it has exceeded a certain limit. So that will takes into account that heavy metals may be present in the Rinsing bath are transferred.

Die Schwermetallkonzentration wird vorzugsweise durch das Messen der Leitfähigkeit der Spülflüssigkeit bestimmt. Falls die Spülflüssigkeit verschiedene Schwermetalle ent­ hält, wird die Strom-Spannungs-Charakteristik gemessen.The heavy metal concentration is preferably determined by the Measuring the conductivity of the rinsing liquid. If the rinsing liquid contains different heavy metals  holds, the current-voltage characteristic is measured.

Eine weitere Möglichkeit zum Messen der Schwermetallkon­ zentration ist eine Meßung der Lichtdurchlässigkeit als eine Funktion der Frequenz und ein Vergleichen mit be­ kannten Frequenzcharakteristika.Another way to measure the heavy metal con concentration is a measurement of light transmission as a function of frequency and a comparison with be knew frequency characteristics.

Die Erfindung wird nachstehend an Hand der Zeichnung näher erläutert, die eine Vorrichtung zur Filmentwicklung zeigt.The invention will now be described with reference to the drawing explained, which shows a device for film development.

Die in der Zeichnung dargestellte Vorrichtung ist mit einem Entwicklerbad 1, einem Fixierbad 2 und einem Spülbad 3 ausgestattet. Darüberhinaus sieht man einen Film 4, der vom Entwicklerbad 1 in das Fixierbad 2 und von dort in das Spülbad 3 geführt wird. Das Spülmittel wird durch einen Kanal in einem geschlossenen Kreislauf eingeleitet, der mit einer UV-Lichtquelle ausgestattet ist, die mög­ licherweise vorkommende Keime abtötet und damit eine Algenbildung verhindert. Es kann jedoch nicht vermieden werden, daß Schwermetalle (Silberionen) in das Spülbad gelangen. Es ist daher wichtig festzustellen, wann die Spülflüssigkeit so verunreinigt ist, daß man sie nicht länger in den Ausguß gießen kann. Die Schwermetallver­ unreinigung der Spülflüssigkeit wird mittels der Leitfähig­ keit an den in das Bad eingetauchten Elektroden 4 und 5 gemessen, da die Schwermetallkonzentration in direkter Beziehung zur Leitfähigkeit steht. Das Spülbad wird aus­ getauscht, wenn die Schwermetallkonzentration einen be­ stimmten Grenzwert überschritten hat. Die Konzentration verschiedener Schwermetalle wird mittels der Strom- Spannungs-Charakteristik gemessen. Die Ionenkonzentration kann auch mittels der Lichtdurchlässigkeit als eine Funk­ tion der Frequenz gemessen werden, wobei eine Frequenz­ charakteristik aufgenommen und mit bekannten Charak­ teristika verglichen wird. Darüberhinaus kann die Reflek­ tion als eine Funktion der Frequenz gemessen werden, sowie die Schallreflektion/Übertragung als Funktion der Frequenz zum Messen der Schwermetallkonzentration herangezogen werden. Diese Meßprinzipien können auch in Verbindung mit anderen Flüssigkeiten angewandt werden.The device shown in the drawing is equipped with a developer bath 1 , a fixing bath 2 and a rinsing bath 3 . In addition, one can see a film 4 which is led from the developer bath 1 into the fixing bath 2 and from there into the rinsing bath 3 . The detergent is introduced through a channel in a closed circuit, which is equipped with a UV light source that kills possibly occurring germs and thus prevents algae formation. However, it cannot be avoided that heavy metals (silver ions) get into the rinsing bath. It is therefore important to determine when the washing liquid is so contaminated that it can no longer be poured into the sink. The heavy metal contamination of the rinsing liquid is measured by means of the conductivity at the electrodes 4 and 5 immersed in the bath, since the heavy metal concentration is directly related to the conductivity. The rinsing bath is replaced when the heavy metal concentration has exceeded a certain limit. The concentration of various heavy metals is measured using the current-voltage characteristic. The ion concentration can also be measured by means of the light transmittance as a function of the frequency, a frequency characteristic being recorded and compared with known characteristics. In addition, the reflection can be measured as a function of the frequency, and the sound reflection / transmission as a function of the frequency can be used to measure the heavy metal concentration. These measuring principles can also be used in conjunction with other liquids.

Erfindungsgemäß ist somit ein Entwicklersystem geschaffen, daß an Orten angewendet werden kann, die keine Wasserhähne und Ausgüsse für die Spülflüssigkeit aufweisen.According to the invention, a developer system is thus created that can be applied in places that do not have taps and have spouts for the rinsing liquid.

Die Zeichnung zeigt darüber hinaus Walzen, die den Weg des Films durch die verschiedenen Bäder bestimmen.The drawing also shows rollers that follow the path of the Determine films through the various baths.

Die Entwicklervorrichtung läßt sich vielfach variieren, ohne dabei von der Idee der Erfindung abzuweichen.The developer device can be varied in many ways, without deviating from the idea of the invention.
