Smartphone-based photometric water analysis

Sustainable water supply, long-term securing of the water cycle, and the protection of our waters are of growing importance due to climate change, pollution, and a growing urban population. To ensure the supply of clean water, a simple but effective on-site analysis of relevant parameters is required to identify contaminations, search for their causes, and initiate countermeasures.

To achieve this, the ZIM project SmartAnalytics is initiated. The aim of the project is the development of a simple and inexpensive smartphone-based measurement system for in situ water analysis. Quantitative proof of relevant parameters should be realized and validated with the simplest means and with a reduced need for chemicals. The camera and flash LED of the smartphone, in combination with a smartphone attachment (from the 3D printer and with a functionalized polymer film), should enable qualitative and quantitative detection of the target molecules (nitrates, phosphates, and ammonium).
