The pH increased rapidly to 3.0 in 10 min. This fast change in pH was due to the presence of ,water,-soluble free ,lime, in the slag. However, the pH increase slowed down once all the free ,lime, was consumed and reached 8.1 after 24 h, resulting in complete neutralisation, indicating that the alkali in the slag has reacted with the ,acid, in the effluent.
