Synthesis of Polyaluminum Chloride Using Alternative and Simple Ultrasonic Vibration System
Advantage of ultrasonic vibrating system over usual method (under simply rapid stirring) for the synthesis of polyaluminum chloride (PACl) is illustrated here. Ultrasonication helps in dispersion of NaOH into the aluminum solution. Coagulants were synthesized at two different OH/Al ratios (1.0 and 2.4). Aluminum present in the coagulants as monomeric, oligomeric and colloidal form was analyzed by Al‐Ferron timed spectroscopy; and 27Al‐NMR spectroscopy. PACls synthesized under ultrasonic vibrating system generated more oligomeric Al species compared to the PACls prepared by usual method, and gave better coagulation/flocculation efficiency.
