Abstract:
Excess of nutrients in irrigation waters leads to eutrophication of the aquatic ecosystem. This process promotes changes in these systems as cyanobacteria grown are uncontrolled. These microorganisms growth at surface impeding the light to pass and consequently the photosynthesis below the surface; the concept of e-eyes designates the assembly of several not fully specific sensors or biosensors in order to obtain a better response to the presence and quantification of the target in this case, optical sensors. In this work, author was implemented an e-eye consisting of silicate and ethylene based polymers doped with nickel oxo-nitrate deposited on glass substrate sand A-ZnO modified glass substrates. The samples were characterized by UV-Vis, FTIR, X-Ray spectroscopies and SEM. The analysis of the results was made using PLS and LASSO techniques as implemented in the R-statistical suite of program.
