## Abstract Extraction of arsenic(III) and arsenic(V) from sulfuric acid solution was studied. Cyanex^®^ 923, Cyanex^®^ 925, dialkyldithiophosphinic acids (Cyanex^®^ 301), hydrophobic glycol (2‐ethylhexane‐1,3‐diol), and hydroxamic acids were used as extractants. The efficiency of extraction depend
A process is described which enables the removal of sulphuric acid from effluents without the addition of chemicals to the effluent. The technique employs an anion selective membrane which separates the acidic effluent from a lime solution. In the case where no current is applied, facilitated tran
