عنوان انگلیسی Application of Nano-lignocellulose for Removal of Nickel Ions from Aqueous Solutions
چکیده انگلیسی مقاله Nickel is one of the toxin heavy metals in surface waters. Developing new approaches aimed at removing heavy metals from aqueous solutions that are simultaneously economical and environmentally friendly is of great importance. The purpose of this study will be using Nano-lignocellulose adsorbent as a natural material to remove nickel heavy metal. In this study, several important environmental parameters were studied such as: pH, adsorbent concentration, duration of exposure, concentration and temperature on the uptake, as well as adsorption and Kinetic isotherms. The maximum adsorption efficiency (99.5%) occurred at pH=6. Optimum contact time was measured 30 minutes, which reflects the short duration of the analysis. Results of researches in the field of adsorption isotherm shown that, the best fit of the experimental data corresponds to the Langmuir isotherm model. Kinetic studies revealed that the process of elimination well matches with pseudo-second-order kinetic model. So, the Nano-lignocellulose has high ability to remove nickel from aqueous solutions and as a new adsorbent could be used in different industrial effluents.
