Procedure

100 ml of an aqueous solution containing sulfuric acid (200 g/l), copper (45 g/l) and arsenic (5.9 g/l) were poured into a 250 ml separatory funnel. Then a 0.3M solution of n-hexylpyrocatechol (100 ml), (a mixture of the two position isomers obtained from the reaction of 1-hexene with excess of pyrocatechol), was added into ESCAID 100; the mixture was strongly stirred for 10' and made then to settle for 30'.
