[Validation of simple analytical equipment for arsenic].
In order to improve the arsenic test method, we investigated the effect of temperature, solar light and masking ions on that test method. As the results, we found that the solar light gave the big damage to the colored reaction on the method. In addition, on comparing the improved method with the arsenic test method of Merckoquant kit by using the water containing 0.01 ppm arsenic as the Japanese guideline for the drinking water, the improved method gave the better analytical value than Merckoquant kit that was not sufficiently determined.
