摘要
The invention relates to an ion gel comprising a hydrogel in an ionic liquid, and a reactive system that changes colour upon reaction with the nitrite. The invention also relates to a microfluidic device comprising a substrate (1) having calibration reservoirs (2) that are separated from one another and include an ion gel, a calibration reservoir (3) of the hydrogel in the ionic liquid, a reservoir (6) for holding a sample to be analysed, connected to a measuring reservoir (4) including an ion gel via a microfluidic channel (5) with a reducing agent, and a measuring reservoir (7) including an ion gel of the invention where a sample to be analysed is held. The invention further relates to methods for producing the ion gel and the device, as well as a method for colorimetrically determining and detecting nitrite and nitrate in contaminated water using the ion gel and the device.
