Third phase formation in the extraction of Th(NO3)4 by tri-2-methyl butyl phosphate from nitric acid media
In the above mentioned paper we had reported a non-linear dependence of limiting organic concentration (LOC) with temperature in the case of tri-2-methyl butyl phosphate in n-tetradecane as well as n-hexadecane diluents. Subsequently we extended the studies to other trialkyl phosphates such as TBP, TiBP, TsBP, TAP, TiAP and TsAP in various diluents (n-decane, n-dodecane, n-tetradecane, n-hexadecane and n-octadecane) and found recently that the dependence was always linear, irrespective of the extractant-diluent combination. This behaviour urged us to have a thorough review of the data reported earlier and when we repeated the studies again in the same systems, we found that the dependence was only linear and not as reported earlier.
We have critically looked into what went wrong in the earlier studies and at present have concluded that wrong temperature calibration/measurement might have induced the same.
We now present the correct data in Tables 1 and 2 and 4. Some parts of the sections “Results and discussion” and “Conclusions” are also modified.
