Abstract

<p>We found that Bathocuproinedisulfonic acid used for colorimetric reagent for copper ion was simply immobilized to cellulose membrane with alginate. Moreover, the color of immobilized Bathocuproinedisulfonic acid was changed with copper ion concentration. In addition, we had reported simple color analyzer by the use of smart device with original application software in previous work. Based on these finding, the objective of study is development of simple analysis for copper ion using original test paper immobilized Bathocuproinedisulfonic acid with alginate and simple color analyzer with smart device. As a results, the detection limit (3σ) was 0.8 ppm. Moreover, this method can be employed for the determination of copper ion in tap water.</p>
