Title : Preparation of nano adsorbent derivative from date palm fronds for the removal of pollutants from aqueous solutions
A new type of nano adsorbent was prepared from date palm fronds with iron oxide nanoparticles (IONPs). Cadmium ions were selected as heavy metals in this work with Concentration of 100 ppm. Four different initial concentrations flasks of cadmium ion were prepared (25, 20, 15, and 10 ppm). The adsorption equilibrium experiments of cadmium onto nano adsorbents were analyzed by the Langmuir, Freundlich, and the Temkin isotherm models, and the equilibrium data fitted well by the Langmuir model with a maximum adsorption capacity of 20 mg/g for Cd (II). The adsorption of cadmium onto prepared nano adsorbent was studied concerning pH and Cd (II) initial concentration in the batch process. The percent removal of cadmium ion onto prepared nano adsorbent decreased with the increase of initial concertation.
- With the widespread use of nanomaterials (NMs) in everyday life, consumer knowledge about the functionality, benefits, and possible dangers of nanotechnology (NT) is still modest. As with any developing technology, its public perception has direct implications on future policies and has to be taken into account by academia and industry alike.
- The fast development of nanotechnology is often defined as a fundamental revolution in technology compared to discovery of antibiotics, television, nuclear weapons, or computer technologies. The workshop discussed the current situation and the development potential of this technology and new technologies as such. The aim was to focus on approaches and first results to identify future skill requirements and new emerging occupations. Nanotechnology is a cross-sectoral and highly interdisciplinary field and its development brings along several completely new tasks, and even jobs and occupations whose requirements have to be identified and transferred into education and training without delay. The workshop attempted to tackle some of the concerns in the area of skill needs.
- Nanotechnology is an interdisciplinary technology of manipulation or self-assembly of individual atoms, molecules, or molecular clusters into structures to create materials and devices with control geometry and at least one component below 100 nm (nanometer) including advanced equipment that allow controlled fabrication, measurement and visualisation with high resolution. Nanotechnology can work in the top-down approach (which means reducing the size of the smallest structures to the nanoscale) or the bottom-up approach (which involves manipulating individual atoms and molecules into nanostructures and more closely integrates chemistry or biology with microelectronics).
