In the present paper, experiments were performed on wastewater containing A and B ions. On the basis of the determination of A content, solution C was added to unmask the B ions. At this point, the solution was dark-brown and the titration was ended when the solution color turned from dark-brown to milk white. This method avoided the troubles of individual titration of A and B ions. In addition, removal of B ions was not required when A ions were titrated. |
