3.1.1. Investigation of TBP: MIBK ratio and effect of HCl. The effect of TBP to MIBK ratio on the extraction behavior of the copper ions in the presence and absence of HCl was investigated (Fig. 1). As seen in Fig. 1, the copper recovery increased with an enhancement in TBP to MIBK ratio and then decreased. The … See more 3.2.1. Effect of buffer solution/sodium acetate in the presence of TBP, MIBK and D2EHPA. In order to investigate the effect of sodium acetate in the presence of … See more In order to investigate the effect of pH on the copper extraction, a series of experiments was conducted. In these experiments, the other parameters optimized were … See more WebThe distribution coefficient (K D) of trace nickel on an iminodiacetate-chelating resin Chelex 100 increased with pH to a peak value close to 2 000 000 ml/g at pH of about 5.At higher pH values the K D dropped to 5000 ml/g due to competition of an unidentified complexing agent.
