Small amounts of phosphonium complexone [1560] are sufficient to increase adhesion to the stratal rock. Table 18-4 illustrates an example for plugging solution with Portland cement and phosphonium complexone. Calcium chloride acts as a regulator of the setting time in the suggested composition. More precisely, phosphonium complexone stands for certain chelating phosphorous compounds (e.g., oxyethylidene diphosphonic acid, nitrilo-trimethyl phosphonic acid, sodium tripolyphosphate, or amiphol) [1540]. The mixture is applicable at low temperatures from 20° to 75° C.

A new type of ceramic membrane electrode that is selective for F" ions has been prepared by sintering LaFg, EuFj, and CaFz at above 1200 °C in an atmosphere of Hf The approximate determination of the F" ion concentration in polluted waters can be made by means of a F ion electrode in the presence of citrate ion however, for an accurate determination a photometric method was applied after separation of F by distillation. The probable composition of the La " -alizarin complexone (H4A)-F complex is said to be La(LaA)4F2. ° Alizarin fluorine blue 5-sulphonate is more soluble in water than the unsulphonated reagent the ternary La -F -complexone absorbs at 583 nm. The application of neutron activation analysis to the determination of fluorine has has been reviewed briefly by Verot and Jaumier. X-Ray photoelectron spectroscopy (p.e.s.) has been used to identify and to provide a quantitative estimate of CF3, CF2, and CF groups on the surface of fluorinated diamond.
