Abstract
The adsorption of Hg(II) cations onto the surface Traganum nudatum roots has been found to be of initial pH, adsorption time and biosorbent dose. The pH 5 is found to be the optimum for the removal of Hg(II) cations from aqueous solution. Three kinetic models such as first-order, pseudo-second order and intra-particle diffusion were used to analyze the Hg(II) cations adsorption process, and the obtained results showed that the pseudo-second-order with correlation coefficient greater than 0.9800 was more suitable than first-order. The obtained results also explained that the intra-particle diffusion is mainly one of the mean determining step of the adsorption mechanism of Hg(II) cations on Traganum nudatum roots
