Integral membrane from PSF/PVA quaternized chitosan cross-linked with RHA silica powder for Li/Mg separation / Nur Syazwanie Izzati Chik

Membrane separation technology is one of the most effective methods to recover Li+from salt-lake brine. Due to its high competition with Mg2+, a new technique known as quaternization process is applied in membrane technology to develop a positively charged membrane which scientifically proven can se...
