Abstract

The solubility ternary system was used to develop a hollow fiber-supported liquid membrane process for the extraction of gold (I) cyanide from electronics industry wastewater. Five kinds of diluents (p-xylene, cyclohexene, 1-dodecanol, n-heptane, and n-dodecane) were applied to the solubility of ternary systems (Aliquat336 + water + diluents) at 303.2 K and atmospheric pressure. 1-dodecanol, p-xylene, and cyclohexane were selected because they are completely soluble in Aliquat336 in any composition. The effects of pH on the feed solution and type of diluent were examined. The highest extraction and stripping percentages of 99.9 and 61.4, respectively, were achieved at a feed solution pH of 10.0 using p-xylene as the best diluent.
