AB  - This work deals with a portable device system applied to detect and classify 
      different metallic ions as proposed and developed, aiming its application for 
      hydrological monitoring systems such as rivers, lakes and groundwater. 
      Considering the system features, a portable colorimetric system was developed by 
      using a multispectral optoelectronic sensor. All the technology of quantification 
      and classification of metallic ions using optoelectronic multispectral sensors 
      was fully integrated in the embedded hardware FPGA ( Field Programmable Gate 
      Array) technology and software based on virtual instrumentation (NI LabView((R))). 
      The system draws on an indicative colorimeter by using the chromogen reagent of 
      1-(2-pyridylazo)-2-naphthol (PAN). The results obtained with the signal 
      processing and pattern analysis using the method of the linear discriminant 
      analysis, allows excellent results during detection and classification of Pb(II), 
      Cd(II), Zn(II), Cu(II), Fe(III) and Ni(II) ions, with almost the same level of 
      performance as for those obtained from the Ultravioled and visible (UV-VIS) 
      spectrophotometers of high spectral resolution.
