Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:

Claeys, Robert Raymond

Abstract:

A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

The determination of titanium, zirconium and hafnium in molybdenum, niobium and tantalum alloys by ion exchange

Creator:

Shakashiro, Mouaffac Hamdy

Abstract:

New alloys containing refractory metals have been developed by the aero-space industry to meet the demand for thermally resistant materials. The chemical analysis of these alloys has been handled successfully by the use of ion exchange. Hydrofluoric acid, either alone or combined with hydrochloric acid, has here-to-fore been used to...
