http://hwb.gov.in/process-description-vspp-synthesis-d2ehpa-mode WebJul 20, 2024 · D2EHPA was more selective to magnesium, so D2EHPA usage resulted in more extraction of magnesium. The presence of lactic acid improved this process, with the highest Mg extraction yield of 88.6%. Increase of the process yield in the presence of lactic acid was due to its complexing role. pH had no strong effect on the magnesium extraction.
http://hwb.gov.in/process-description-vspp-synthesis-d2ehpa-mode WebAround 96.6% of Mn(II) was extracted using two extraction stages at O/A ratio of 1:1 and pHe (equilibrium pH) of 4. Furthermore, FTIR method showed that TBP and D2EHPA were bonding via a hydrogen bond. In addition, by slope analysis method the stoichiometric coefficient of Mn was found to be 4 for D2EHPA and 1 for TBP. Show less
