Mechanism of interaction and removal of zinc with lignocellulosic adsorbents, closing the cycle with a soil conditioner

Batch experiments were performed to remove Zn2+ by adsorption process using organic residuals (pistachio, peanut, and almond) as an adsorbent. The adsorbents were characterized by FTIR spectra, SEM images, and elemental analysis. Optimum adsorption of Zn2+ was obtained at pH 6 with a contact time of...
