Abstract EN
By use crown ether DB18C6 and from acidic HCl media extracted Fe3+ ion as ion association complex by application cloud point extraction methodology after change Fe3+ into FeCl4- , this study show 1.2M HCl was the optimum concentration in precence 5×10 -2 M NaCl and 1×10-4 M Crown ether DB18C6 as well as show 0.5mL of Nonionic surfactant 1% TritonX100 was necessary to obtained higher extraction efficiency , so that thermodynamic study illustrate 85ºC was favorable temperature for extraction according to CPE method in addition to needing heating the solution in electrostatic water bath at 85 ºC for 15 minutes .
Thermodynamic data was ∆Hex=0.159 KJ mol-1 , ∆Gex=-62.43 KJ mol-1 , ∆Sex=174.83J mol-1 K-1 , experimental application offer the more probable stracture of ion pair association complex extracted was [Na DB18C6]+ ; FeCl4- , there are another empirical application for this study in real samples .
