Control on the management of wastewater containing toxic heavy metals are being tightened, but the water to be managed is distributed in various places, and the labor and cost of analyzing collected water in a laboratory is enormous. Therefore, it is required to determine the quantify of heavy metals in water with high sensitivity, low cost and simple on-site. In this study, we serched the possibility of on-site analysis that combines Homogeneousu liquid-liquid extraction, which can make the heavy metals concentrated microdroplets with a simple operation procedure, and color information measurement using a smart device.
