Modified superparamagnetic nanocomposite microparticles for highly selective Hg(II) or Cu(II) separation and recovery from aqueous solutions.

ACS Appl. Mater. Interfaces 4(10) , 5633-42, (2012)

The synthesis of a reusable, magnetically switchable nanocomposite microparticle, which can be modified to selectively extract and recover Hg(II) or Cu(II) from water, is reported. Superparamagnetic i...

Utilization of a low cost agro-residue for production of coagulant aids and their applications.

J. Hazard. Mater. 186(2-3) , 1200-5, (2011)

Different samples of rice husk ash (RHA) and sodium silicate were prepared and characterized using FTIR, NFTIR and XRD. The selected sample of RHA was obtained by calcination of untreated rice husk (R...

Performance of lime-BHA solidified plating sludge in the presence of Na2SiO3 and Na2CO3.

J. Environ. Manage. 92(9) , 2222-8, (2011)

This research investigated the performance of lime-BHA (black rice husk ash) solidified plating sludge with 2 wt% NaO from Na(2)SiO(3) and Na(2)CO(3) at the level of 0, 30 and 50 wt%. The sludge was e...
