Adsorption and biosorption for pollutant removal

Heavy metalsHeavy metals stay in the environment for large periods of time, which contribute to them being highly toxic and are associated to illness in human beings and biodiversity reduction. The present paper used Lactuca sativa L. and Lolium perenne to remove heavy metalsHeavy metals from galvanoplasticGalvanoplastic waste polluted soil. Nickel, Cobalt, and Iron (adsorbents) from galvanoplasticGalvanoplastic waste were chosen as parameters in the biosorbents (roots, stem, and leaves). Particle size phytoextracted by L. sativa L. and L. perenne were analyzed using SEMSEM (Scanning Electron Microscopy) and Atomic Absorption Spectroscopy (AA). It was determined that L. sativa L. has a greater absorption capacity, but a lower intrinsic velocity than L. perenne . The greatest survival time was presented by L. perenne .
