主　　题：iodate liquid waveguide capillary cell spectrophotometric determination 

摘      要：A new spectrophotometric method based on a liquid waveguide capillary cell for an enhanced detection was developed to measure nanomolar iodate *** method has a detection limit and precision of 1-2 nmol/L,which is equivalent to 10%that of conventional methods,a recovery of 97.7%-104.0%,and a working range of 10-120 nmol/*** samples were collected from three estuaries and one coastal ocean for testing,and the proposed technique detected as low as 11 nmol/L and 18 nmol/L iodate in these *** newly developed method is helpful in understanding the biogeochemical cycle of iodine in nature.
