Abstract
  Removal of heavy metals from waste water is a need of the hour. Titanium dioxide (TiO2) nanoparticles were functionalized using succinic anhydride (SA) and adsorption of copper (II) on SA functionalized TiO2 nanoparticles (TiOSA) was carried out. The adsorption of Cu (II) on TiOSA was estimated with ...  Read More

https://doi.org/10.22090/jwent.2019.03.004

Abstract
  In this study, polysulfone (PSf) nanocomposite membranes embedded with functionalized nanodiamond (ND) were prepared via Non-Solvent Induced Phase Separation (NIPS) method. ND nanoparticles were silanized by using the esterification reaction of hydrolyzed vinyltrimethoxysilane (VTS) in alcoholic solution ...  Read More
