β¦ Synopsis
A flow-mJectlon method for the determmatlon of dissolved organic carbon concentrations m natural and waste waters IS described The analysis IS based on m-hne W photo-oxldatlon of dissolved orgamc carbon (DOC) to carbon dloxlde with spectrophotometrlc detectlon The method IS rapld (ca 45 samples h-l), has a linear response from 0 1 to 2 0 mg C I-' and a detectlon hnut of ca 0 1 mg C 1-l Minor moddkatlons m the mamfold can extend the linear response range to 80 rng C I-' with a shght increase m detectlon hmlt, makmg the techmque well smted for the deternunatlon of DOC m natural and waste waters

The choice of model compounds for checking the recovery of dissolved organic and total dissolved phosphorus in natural waters is discussed. Ten compounds were compared for their recovery in fresh and seawater. Four different oxidative procedures were used: acidic and alkaline persulfate oxidation, c

The concentration of chloride ions in natural and waste waters was determined by a flow-injection method using a column packed with silver chloranilate powder. Ethanol-water-0.1 M sodium acetate buffer (pH 5.57) (5 + 4 + 1, v/v/v) was used as the carrier at a flow-rate of 2 ml min-1. The chloranilat

## Abstract Inorganic mercury and methylmercury are determined in natural waters by injecting the filtered samples onto a low cost commercial flow injection system in which an anion exchange microcolumn is inserted after the injection loop (FIAβIE). If hydrochloric acid is used as the carrier solut
