Paper Abstract

In this work we studied the behavior of an in fiber Mach-Zehnder interferometer for salinity measurements. The salt species used are KCl, NaCl e NaCOOH (organic salt) within the concentration range from 3 g.L-1 to 150 g.L-1. The results are compared with traditional salinity measurement methods (conductivity and refractive index) and show that the device can distinguish and identify the concentration of each species saline.
