Abstract

The Texas Air Control Board describes a method that determines ppb (parts-per-billion) levels of H/sub 2/S in air by trapping out the H/sub 2/S in an aqueous NaOH/ascorbic acid absorber and titrating the resulting sulfide ion with a standard CdSO/sub 4/ solution, using a sulfide-ion-selective electrode as an indicator. The method produces linear and accurate results for 50-1000 ppb H/sub 2/S in air; the precision is excellent and no interference occurs from HO/sub 2/, SO/sub 2/, or O/sub 3/.

Accelerated potentiometric titration of sulfides and cyanides

Journal Article Dyatel, S G ; Peskova, D V ; Zyskina, F A - Coke Chem. USSR (Engl. Transl.); (United States)

Titration with a mercury (II) nitrate solution and potentiometric end-point indication have been suggested for analysis of carbonization-plant effluents to determine their hydrogen sulfide, hydrogen cyanide, and bound and free ammonia contents. This technique, which permits differential determination of the components in a single solution aliquot without separation has a number of drawbacks. For example, the thin-layer platinum electrode used as an indicator rapidly goes out of adjustment and its working surface cannot be regenerated in the normal plant laboratory. Direct use of a silver chloride comparison electrode for determination of chloride ions is not permissible. Use of a titrantmore »« less
RAPID DETERMINATION OF Zn IN Al ALLOYS BY EDTA TITRATION METHOD (in Japanese)

Journal Article Wakamatsu, S - Nippon Kinzoku Gakkaishi (Japan)

Zinc in the presence of aluminum and tin was titrated with EDTA. To avoid the interference of aluminum and tin, NH/sub 4/F was used. The method was successfully applied to the determination of zinc in aluminum alloys. The procedure is as follows: Weigh a 2 g sample into a beaker and dissolve it in 30ml of 20% NaOH solution and 5ml of 30% H/sub 2/O/sub 2/. After boiling out the excess H/sub 2/O/sub 2/, add Na/sub 2/S solution, cool, dilute to volume in a 500- ml volumetric flask, and filter through a dry filter paper. Fe, Mn, Cu, Ni, Ti,more »« less
Separation and determination of parts-per-billion concentrations of gallium in biological materials

Journal Article Scott, N ; Carter, D E ; Fernando, Q - Anal. Chem.; (United States)

Gallium is separated from an aqueous digest of a biological matrix, by the selective extraction of the ion pair GaCl/sub 4//sup -/ x R/sub 4/N/sup +/, into a hexane-methyl isobutyl ketone mixture (R/sub 4/N/sup +/ represents the methyltricaprylammonium ion). The extracted gallium species reacts with the ligand, 1,5-bis(salicylidene)-thiocarbohydrazone, to form a complex that fluoresces at 440 nm when the excitation wavelength is 395 nm. This fluorometric method has been used to determine 0.10-40 ppb of gallium in biological materials with a relative precision of 7%. The principal interferences with the fluorometric method in aqueous solutions are Fe/sup 3 +/, Fe/supmore »« less

Rapid potentiometric determination of carbonates in the presence of sulfides, cyanides and free ammonia

Journal Article Dyatel, G S ; Teikhrib, T K ; Kusova, A I - Coke Chem. USSR (Engl. Transl.); (United States)

Carbon dioxide in aqueous solutions may be present in the undissociated form, and also in the form of hydrocarbonate and carbonate ions. Coking plant liquors, containing free NH/sub 3/ (the ammonia and supernatant liquors), have a pH of 9 to 10. Under these conditions the concentration of free CO/sub 2/ is negligible and its principal form of existence is as hydrocarbonate ions. CO/sub 2/ in coking plant liquors is usually determined by a prolonged and laborious method based on separation of the carbonates by precipitation. The use of such a complex method is a result of the simultaneous presence ofmore »« less
DETERMINATION OF CHLORIDE IN URANIUM-BEARING MATERIALS BY A POTENTIOMETRIC TITRATION METHOD

Technical Report Laux, P G ; Brown, E A

A direct potentiometric titration method is described for the determination of chloride in the range of 0.005 to 0.15% in uranium-bearing feed materials. The titration is carried out to a predetermined equivalence potential in a 95% methanol--5% nitric acid medium. A silver wire-saturated calomel electrode system is used. The method is rapid, since no preliminary separation of the chloride is required. The major interferences for the titration are iron (III), vanadium (V), permanganate, nitrite, bromide, and iodide. The interference of all ions except bromide and iodide is prevented by the addition of ascorbic acid or ammonium hydroxide. A comparative studymore »« less
