| 抄録: | Recent studies indicate the existence in natural waters of 'hidden' arsenic which had previously been undetected by hydride generation technique. A speciation method for arsenic species has been developed in which hidden arsenic was classified into two fractions by their lability to the photochemical degradation procedure: the ultraviolet-labile fraction and the ultraviolet-resistant fraction. We discussed the hidden arsenic fraction as the key to explaining arsenic speciation in natural waters. |
