1039/9781849735001-00030 36 Chapter 3 wastewaters by dried plants was 94% for Cd(II), 92% for Cu(II), 99% for Pb(II), 97% for Zn, 100% for NO32– and 77% for PO43– ions. For all heavy metal ions, the uptake eﬃciency of the studied plants ranged as C. edulis4W. frutescens4L. arborescens; however, the diﬀerences were rather small. 28 proposed the use of Agave sisalana (sisal ﬁber) as a natural adsorbent for Pb(II) and Cd(II) ion biosorption from natural waters. Flame atomic absorption spectrometry was used for the quantitative determination of Pb(II) and Cd(II) adsorption on the solid phase.

It uses perennial and non-harvested plants to suppress the vertical migration of pollutants through absorption and accumulation by roots or precipitation in the rhizosphere. So, the toxic sites are stabilized by plants that serve as ground cover, thereby reducing the distribution of the toxic metals to other areas. The tolerance ability of a plant plays a crucial role in this process, as disposal of the hazardous material or the biomass is not required. 3 Phytovolatilization Use of plant material to modify and transform the metal contaminants to less toxic species and subsequently releasing them into the atmosphere is known as phytovolatilization.
