| Outline of Final Research Achievements |
Expensive analytical equipments are necessary to determine various substances with high sensitivity. In this work, solid-phase extraction with a membrane filter was used to concentrate the substances in the sample, such as phosphorous, copper, and manganese. They were colored by the specific reagents and were collected on the filter. We have developed an LED-based, palm-top size reflective absorbance detector to measure the concentration of the substance on the filter directly. Thus the high sensitivity for the determination of phosphorous in natural water and ferrocyanide in common salt, and so on, has been attained without an expensive equipment with the combination of this detector and solid-state extraction.
