Further advances in dissolved oxygen microanalysis. II. Sources of interference

Autor: E. C. Potter, G. E. Everitt

Publikováno v: Journal of Applied Chemistry. 9:645-650

The interfering effects of various substances on the Winkler reaction as applied to dissolved oxygen microanalysis have been elucidated. Ammonia, cyclohexylamine and morpholine do not interfere at concentrations encountered in power-station practice.

Some analytical implications of the interaction between the water and oxygen permeabilities of polymers

Autor: R. G. Thompson, E. C. Potter, G. E. Everitt

Publikováno v: Journal of Applied Chemistry. 15:398-402

Tubes of polythene, polypropylene, furfural polymer (‘Tygon’) or polytetrafluoroethylene are normally permeable to atmospheric oxygen when deoxygenated water flows through them. Both polypropylene and Tygon can achieve a state of impermeability a

Further advances in dissolved oxygen micro analysis. I. Small-scale water sampling vessels and amperometric titrations

Autor: E. C. Potter, G. E. Everitt

Publikováno v: Journal of Biochemical Toxicology. 9:642-645

The development is described of 12 1/2 ml. water-sampling vessels and amperometric titrations of iodine in 15 ml. total volume. Application of these techniques to dissolved oxygen analysis enables a precision of ± 0.002 p.p.m. to be achieved with a

Further advances in dissolved oxygen microanalysis. III. Interference during water-sampling

Autor: E. C. Potter, G. E. Everitt

Publikováno v: Journal of Biochemical Toxicology. 10:48-56

Dissolved oxygen will pass through most of the common types of plastic tubing. Materials unsuitable for use in sampling water for dissolved oxygen microanalysis are red and black natural rubber and silicone rubber. Polythene tubing has been found per
