removal of methylene blue dye by application of polyaniline nano composite from aqueous solutions
Authors
abstract
this paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (mb) dye from aqueous solutions. polyaniline coated onto sawdust (termedas pan/sd) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (hc1) media. adsorptionexperiments were carried out using batch system. the effects of different system variablessuch adsorbent dose, initial dye concentration, ph, contact time were then studied. it wasfound that pan/sd is efficient and cost effective adsorbents for removal of mb dye fromaqueous solutions.
