## Abstract An ionβexchange technique is shown to be effective for removing interference by ferrous ion in the Winkler reaction. A referee method for the determination of dissolved oxygen in water is described incorporating full allowance for interfering substances and tests for bias and precision.

A simple flow-injection method for the automatic photometric determination of low concentrations of dissolved oxygen in waters was developed. The method uses Methylene Blue immobilized on a cationic exchange resin packed into a flow-cell located in the spectrophotometer, where the leuco form of the
## Abstract The part played by oxygen dissolved in feed water in the corrosion of marine boilers has long been known, and deβaerating plants to eliminate or reduce the oxygen content have been installed wherever a closed feed system exists. This method is designed to enable the determination of dis
