Abstract

<p>In this paper, we described development and evaluation of simple color analysis using smart device such as smart phone and tablet as color analyzer. We try to determine nitrate ion by combination with naphthylethylenediamine colorimetric method. As a result, 0.1 to 2.0 ppm of nitrate ion could be determined by proposed method. Moreover, the proposed method shows same performance compared with commercial portable type of color analyzer. The proposed method was able to be realized not only simplification of analytical instrument, but also display analytical date on map. By use of this function, distribution of concentration is able to be easily measured. These results indicate that the proposed smart device color analyzer is able to contribute water environment in the arid land area.</p>
