A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...

Pinewood sawdust was pyrolyzed to create a micro-nanocarbon. The adsorbent’s particle size reduced during ball milling procedure improve the surface area and encourage porosity growth. synergistic effects of micro-nano-adsorbent-reinforced poly(lactic acid) (PLA) composites were investigated by analyzing efficiency rheological process. properties prepared also examined using various characteriz...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

The application of poly (vinyl alcohol) (PVA) in an unmodified form as an adsorbent for methylene blue (MB) dye removal in waste water at 303–333K was investigated. Effects of operational parameters such as adsorbent dosage, initial dye concentration and pH were determined for optimum conditions for maximum dye removal. Results obtained showed that dye removal efficiency increases as the amount...
