DEVELOPMENT OF THE CONDITIONS FOR STORING THALLIUM AMALGAM

It has been established that lNH2SO4 solution and distilled water can be used as a protective medium for long-term storage (30-40 days) of thallium amalgam eutectic composition (8.6 mas.%), without sliming its surface an insignificant change concentration. An inverse dependence between the decomposition reaction rate ratio volume per unit contact (V:S), which corresponds to height liquid layer (h) above amalgam, is observed. At h ~ 2.5 cm higher, becomes stabilized. The value metal loss during 10-15 days does not exceed 0.5-1.0 mas.% initial content in amalgam. shown dissolution from rather low, sulfuric acid it only slightly higher than with all S:V ratios. A similar picture observed upon same media open vessel; difference consists K (Table 4). Thus, = 1:2.5, vessel makes up 10,5.1011 mol/cm2.sec, H2O – 7.3.1011 whereas closed 1,9.1011 mol/cm2. sec, 1.5.1011 mol/cm2.sec. For 40 (8.54 mas.%) 1NH2SO4 1.3 mas.%, - 1 mas.%. quantity dissolved increases proportion experiment duration, characteristic zero-order reaction, this ratios 1:1 1:7. Besides, possibility use some saturated hydrocarbons, wherein no occurs, wash shown.
