“…The precipitate flotation process is pH dependent: below pH 6. 3, soluble chromium species become appreciable and the flotation results agree with calculated soluble chromium concentrations; above pH 9. 7, the charge of the precipitate i s reversed, as indicated by surface potential measurements.…”

more dense than the ethane-rich liquid over the entire threephase region. DATA ANALYSISIsothermal vapor and liquid composition data for the carbon monoxide-propane system were fitted to empirical equations in the form of power series in pressure. The mathematical form of the vapor and liquid polynomials, as well as the least-squares constants, are presented by Trust (7).The average standard deviation of the experimental liquid phase data from the curve was 0.28 mole % carbon monoxide. For the vapor phase the average standard deviation of the experimental data from the curves was 0.40 mole % propane.The experimental data for the carbon monoxide-ethane system were not fitted to equations.

Coflotation of ¹³⁴Cs from Radioactive Process Waste Water

Cesium, coprecipitated with copper ferrocyanide, can be readily removed from radioactive process waste water using sodium lauryl sulphate (NaLS), cetyl trimethyl ammonium bromide (CTAB) or gelatin (Gl) as collector. In addition to the effect of the collector type on the percentage removal and volume reduction, the effects of the pH of three distinct Cu 2 + : Fe(CN)J ~ ratios and of different ageing periods of the cesium-copper ferrocyanide-water systems have been established. With NaLS, CTAB and Gl successful removals could be achieved in the pH ranges 3-7.5, 5.0-10.5 and 5.5-9.0 respectively. The results are discussed in terms of the ionization of the active groups of the collectors and of the electrical state of the precipitate.
