We have developed an improved fast and sequential protocol that permits the determination of low concentrations of nitrite and nitrate in aquatic samples using small volumes. It is ideal to analyse large sets of samples with different characteristics, since it is enough a small amount of water the volume and cost of reagents and consumables are reduced.
Description of the technology
This fast and efficient method to determine sequentially the levels of nitrite and nitrate in water samples in low concentrations (<0.05 - 30 μM ). The application of this method would render possible the design of portable measuring units to determine the concentrations of nitrite and nitrate in water samples. Its owner offers the license to those able to develope commercial or industrial applications of this scientific result.
Specifications
Comparison of the patented method with the established cadmium column method using samples from a variety of salinities and environments (fresh water reservoir, sediment pore water, estuarine water samples and samples from an acid mine drainage impacted reservoir) showed good agreement between the two methods (paired t-test , t = -0736, p = 0.472, n = 17). Proving that the vanadium reduction method using spectrophotometry does not bias the results.
Main advantages of its use
Applications
The university of Cadiz is a state university with 4 campuses and more than 2,000 lecturers. It is located at South Spain and it is one of the nine state universities in Andalusia, Spain. We have in our portfolio more than 100 patents for licensing, looking for potential investors.
