Abstract
Throughout the world, many water resources are polluted by industrial and domestic
effluents, acid mine drainage, etc. The increasing awareness and concern about the
environment has motivated in the recent years extensive research into developing new
efficient, cost effective and environmentally sound technologies to treat industrial solutions
bearing metals and sludges. From the literature review, much research has been, and is still being devoted to the
performance of solvent extraction (SX) of aluminium or sulphate in acidic solutions and how
to improve such performance. There is a general lack of information on liquid-liquid
extraction of aluminium or sulphate in an alkaline solution. Thus, the need for a systematic
investigation into the solvent extraction of aluminium and sulphate in an alkaline medium was
important. This thesis focuses on the study of solvent extraction of aluminium and sulphate
from alkaline solutions using Trioctylmethylammonium chloride, (Aliquat 336), in Kerosene as
diluent.
