Zusammenfassung: | The invention is based on a measuring sensor for water toxicity and consists of a network of micro-electrodes coated with a membrane and a biofilm. The network of micro-electrodes can be standard, and its operation with a single electrode is possible, although this would lead to a loss of sensitivity. The membrane is used to prevent passivation of the electrode by the bacteria present in the water, and it will be used in one of the possible embodiments "nafion", although it is also possible that the sensor works without a membrane, but this would go against an operation suitable. By measuring the oxygen (related to the respiration of the bacteria) the contamination of the water can be determined, since the presence of toxic substances inhibits the respiration of the bacteria.

La invención se basa en un sensor de medida para la toxidad del agua y consiste en una red de micro-electrodos recubiertos de una membrana y de un biofilm. La red de micro-electrodos puede ser estándar, y es posible su funcionamiento con un único electrodo, aunque ello acarrearía una perdida de sensibilidad. La membrana se usa para evitar la pasivación del electrodo por las bacterias presentes en el agua, y se utilizará en una de las realizaciones posibles "Nafion", aunque también es posible que el sensor trabaje sin membrana, pero ello iría en contra de un funcionamiento adecuado. Mediante la medida del oxígeno (relacionada con la respiración de las bacterias) se puede determinar la contaminación de las aguas, dado que la presencia de sustancias tóxicas inhibe la respiración de las bacterias. |
