The procedure described for the determination of hydrogen peroxide in aqueous solution, at concentrations in the range 1-120X 10d6 mol l', is based on reduction of copper (II) ions by hydrogen peroxide in the presence of excess of 2,9-dimethyl-l,lO-phenanthroline (DMP) to form the copper (I) -DMP co

Techniques are described for the pyrohydrolysis of a range of sample materials in a silica tube furnace. Samples are mixed with a catalyst and combusted at 1200Β°C in a stream of oxygen and steam, and the liberated fluorine is absorbed in solutions appropriate to either ion-selective electrode or ion
A method is described for determining the diffusion coefficients of small solutes in limited volumes (approximately equal to 4-9 ml) of fluid. Diffusion is measured in a three-chamber diffusion cell across a central unstirred compartment. Compartments are separated by nitrocellulose membranes. The i
