โœฆ Synopsis

This work deals with a simple, rapid, and efficacious design for the measurement of 137Cs in seawater . An adsorption filter is fabricated by coating copper(II) hexacyanoferrate(II) (CuCF) onto a densely twilled nylon cloth . The CuCF-nylon cloth filter is cut into round pieces and screwed into a polyethylene (PE) column . The 137Cs-containing seawater sample is allowed to pass through the CuCF-nylon cloth filter into the column and 137Cs in seawater can thus be efficiently adsorbed . The analysis for less than gCi level of 137 Cs in 41 seawater is illustrated to have a recovery better than 97% . The detection limit for 137 Cs in seawater can be greatly improved by the enrichment of 137Cs on the adsorption filter .

## Abstract A novel inhibitory kinetic fluorimetric method for the determination of trace methomyl was proposed. It was shown that the Fenton reagent oxidized rhodamine B in acid medium which enabled the fluorescence quenching of the latter. The presence of trace methomyl clearly inhibited the reac
