The influences of dispersant type, supersonic time and concentration on the dispersion property of the nano-aluminium powders in glycol water were systematically studied by using Sodium dodecyl sulfate (SDS),cetyl trimethyl ammonium bromide (CTAB) and sodium hexa metah posphate(SHMP)as dispersants. During the first stage of the experiments, influences of dispersant type and ultrasonic time with these dispersants were evaluated. The next stage of the study was focused on SHMP concentration. The influence of SHMP concentration was assessed. The results show that with the increasing of ultrasonic time, the dispersion property of nano-aluminum powders first increases and then decreases, and SHMP is the best one. The excellent dispersing condition on the dispersion property of nano-aluminium is: 5g/L SHMP and 50 min ultrasonic vibration.

Flotation separation of strontium (Sr) from wastewater via phosphate precipitation was investigated. While 37.33% of Sr precipitated at highly alkaline pH in the absence of PO43−, it completely precipitated as Sr3(PO4)2 at a molar ratio ([PO43−]:[Sr2+]) of 0.62 at a lower pH value. The presence of Ca2+ hindered Sr precipitation, yet it could be overcome by increasing the PO43− dose. Sodium dodecyl sulfate (SDS) was a better collector for dispersed air flotation of Sr3(PO4)2 than cetyl trimethyl ammonium bromide, or mixed collector systems of SDS and saponin. The highest separation efficiency of 97.5% was achieved at an SDS dose of 40 mg/L. The main mechanism in the precipitate flotation is adsorption of anionic SDS on the positively charged surface of colloidal Sr3(PO4)2 via electrostatic interaction. SDS enhanced the aggregation of Sr3(PO4)2 precipitates as the size increased from 1.65 to 28.0 μm, which was beneficial to separation as well.
