摘要: The presence of inorganic pollutants such as metal ions (Ni2+, Pb2+, Cr6+) in water, probably by long-term geochemical changes and from the effluents various industries, causes diseases disorders (e.g., cancer, neurodegenerative diseases, muscular dystrophy, hepatitis, multiple sclerosis). Conventional methods for their removal are limited technical economic barriers. In biosorption, low-cost efficient biomaterials used this purpose. study, Brassica Campestris stems agriculture waste has been Ni2+, Cr6+ Pb2+ an aqueous solution containing all ions. Effect different parameters, e.g., pH, contact time, ion initial concentration, adsorbent dose, agitation rate temperature were analyzed optimized. worked well compared to Ni2+. atomic absorption spectrophotometer (AAS) FTIR investigation before after shows a clear difference capability. highest adsorption percentage was found at 98%, 91%, 49% respectively, under optimized parameters. Furthermore, Langmuir isotherm better fitting experimental data than that Freundlich isotherm.
