Abstract

Whereas, Fe (III) is easily extracted using di (2-ethylhexyl) phosphoric acid (D2EHPA), it is hard to strip it from the organic phase. It is well known that Fe (II) is readily stripped from( D2EHPA), so a reduction of ferric to ferrous iron could be away to solve this problem. In this work, the conventional way of stripping using acidic solutions such as H2SO. and HCl has been studied. Fe (III) stripping was found to increase with increasing acid concentration. The optimum acid concentration required is 10 N and S N for H2SO, and HCT, respectively. Also, reductive stripping in vacuum has been studied by using SHG zinc powder as a reducing agent. The optimisation of operating conditions, such as degree of vacuum, acid concentration and quantity of added zinc, has been made. The experiments showed that a stripping yield greater than 90% in only one stage can be achieved, depending on A/O ratio, at 60 kPa of pressure. Iron reduction and stripping live been done simultaneously.
