BANANA TRUNK FIBERS AS AN EFFICIENT BIOSORBENT FOR THE REMOVAL OF Cd(II), Cu(II), Fe(II) AND Zn(II) FROM AQUEOUS SOLUTIONS

The biosorption of Cd(II), Cu(II), Fe(II) and Zn(II) from aqueous solutions by an agrowaste, namely banana trunk fibers (BTF), was investigated. The effect of pH, contact time, metal ions concentration, adsorbent dose and change in [M2+]/biomass were studied at ambient temperature (25 °C). The equih...
