Immobilization Of Humic Acid On Chitosan Using Protected Cross-Linking Reaction Method And Its Application As Sorbent For Pb(Ii), Cd (Ii), And Cr(Lll)
Immobilization of humic acid (HA) on chitosan has been done by using a protected cross-linking reaction method and the product was then utilized as soment for Pb(II), Cd(II), and Cr(lll). HA was cross-linked with chitosan by using glutaraldehyde in order to obtain soment insoluble in aqueous acidic...
