Abstract Inductively Coupled Plasma Atomic Emission Spectrometry (ICP) was adopted for direct analysis of silicate in seawater, eliminating necessity for pre-treatment. Via this method, the determination of silicate is rapid and easy compared with conventional methods of colorimetry. In seawater analysis, a decrease of sensitivity of about 24% was observed due to interference by coexisting elements, mainly Na. Examination of the analytical conditions revealed a detection limit of 0.3 μM Si, and precisions of approximately 3.2, 2.0 and 1.3% for Si levels of 4, 15 and 94 μM, respectively. Using this method, silicate determination in the East China Sea was attempted.
