抄録

A flow system using a 10-cm absorption tube (2.5 mm diameter) has been designed for highly sensitive spectrophotometric analysis of aqueous samples. A hand-made flow system connected to the absorption tube was attached to a commercial double-beam spectrophotometer. The system was applied to the phenylfluorone method using a cetylpyridinium chloride dispersing agent for the determination of tin. In the present system using 0.3 ml of each sample and reagent solutions, the time for a measurement was reduced to 3 min at room temperature, compared to 30 min at 40°C in the conventional method (using a 10 ml reaction solution). The detection limit was about 1 ng/ml, approximately 1/10 of that in the conventional method. The method was successfully applied to rain samples, and was allowed to follow any change in the tin concentration with the elapsed time of precipitation.
