Why in news?
Researchers from the University of Tasmania, in collaboration with the company Aquamonitrix, have developed a compact ion chromatograph called “Aquamonitrix” capable of accurately measuring nitrate and nitrite concentrations in water on‑site. The device aims to make water testing simpler and more accessible for environmental monitoring and education.
How does it work?
An ion chromatograph separates charged particles (ions) in a sample and quantifies them. Traditional instruments are bulky and need sophisticated laboratories. Aquamonitrix miniaturises the technology:
- Uses a low‑pressure battery‑powered pump and sodium chloride solution as a carrier to move the sample through a separation column.
- On‑board detectors measure the concentration of nitrate and nitrite as distinct peaks.
- The entire system fits in a portable case and can be operated by non‑experts.
Features and benefits
- Environment‑friendly: avoids toxic chemicals and consumes little energy.
- Portable and user‑friendly: weighs only a few kilograms and runs on batteries.
- Real‑time measurements: provides results on‑site, allowing quick corrective action.
- Educational tool: enables students to learn about water chemistry through hands‑on experience.
Applications
- Environmental monitoring: Detecting nitrate pollution in rivers, groundwater and agricultural runoff.
- Agriculture: Helping farmers manage fertiliser use more efficiently.
- Water treatment: Monitoring drinking water quality and wastewater treatment plants.
- Research: Portable instruments can support field studies in remote areas.
Significance for India
Nitrate contamination is a pressing problem in many parts of India due to excessive fertiliser use and poor waste management. Affordable portable devices like Aquamonitrix can empower rural communities, local bodies and schools to test water regularly and take corrective measures.
