| description | ABSTRACT
The existence of the AuCI4 ion as the function of pH before performing the extraction of gold in the system of tetra N-butylammonium chloride (TBACI) - chloroform has been studied. The experimental data showed that at pH of 5-10, AuCI4 ion would be hydrolyzed, whereas at pH of 11 - 14, an amorf dark-brown precipitate was appeared. The emount of gold in the solution at pH 14 before extraction was around 70 %.
Extraction had been carried out by investigating the influence of pH and TBACI concentration on the extraction efficiency. The experimental result indicated that TBAC1 was a very efficient extractant for the extraction of gold from aqueous halide with an efficiency higher than 99 %. The extraction in the TBAAC1-chloroform was effective at pH of 0 -4 with minimum concentration of TBAC110-3 NI, and the calculated K. (extraction constant) was 5.07
x 104.
Key Words: Extraction, extraction efficiency, extraction constant. |
