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.

Dodecyl Sulfate

Hexadecyl trimethyl ammonium bromide (CTAB) was used as simulated substance of organic amine wastewater, the adsorption of sodium dodecyl sulfate (SDS) intercalated ZnAl-LDH and MgFe-LDH [ZnAl (SDS)-LDH and MgFe (SDS)-LDH] on it are studied. These two kinds of LDHs all have good adsorption ability on CTAB, the COD removal degree of ZnAl (SDS)-LDH and MgFe (SDS)-LDH on CTAB can be high up to 94% and 96% due to the static electric attraction and the hydrophobic interaction between the SDS and CTAB.
