Study of Transmission Electromicroscope of Polyaluminum Chloride
Three series of polyaluminum chloride with aluminum concentration 2.50 mol/L (A, C, D series)have been prepared under simulated industrial production conditions and a series with Al concentration 0.150~0.336 mol/L has been obtained using a low-speed alkaline titrimetry(B series). The test results of transmission electromicroscope indicate that the particles of A, C and D series specimens are in the dispersing state, there no particles appear in the flocculating mass and branching state, while the particles of B series specimens at middle and lower basicity appear in the flocculating mass and branching state, at hingher basicity they are in the dispersing state.
