Abstract

The use of biomass as selective membranes for chemical species in modified electrodes has been advancing in the last few years, with chitosan being a cheap, versatile and available material. This work describes the construction of an electrode modified with chitosan with a sensor to the phosphate ions. Different methodologies of preparation of these electrodes were studied, whereas the one built with chitosan microspheres and ionic conductor nitrate was the most efficient, with correlation above 0.99 and linear curve between 5.1 x 10^-5 to 1.3 x 10^-3 mol L^-1. There is no significant interference of iodide and bromide ions, but the chloride ions present small interference.
