Abstract

Nickel metal extraction from hydrotreating catalyst waste is an attempt to recover purer Ni metal using extraction process. Emulsion liquid membrane with double surfactant was chosen because this extraction method has the highest separation efficiency, shorter time of process, and simple process steps. The double surfactant that was varied in this study was a mixture of Span 80 with Tween 20 and Span 80 with Tween 80. The experimental results showed that the best nickel extraction was obtained using Cyanex 272 extract with a concentration of 0.06 M, 8% (w / v) surfactant double Span 80 with Tween 20, with an internal phase ratio and organic phase of 1: 1. The extraction process lasts for 15 minutes with a stirring speed of 250 rpm.
