Synthesis, characterization, antimicrobial activity and applications of polyanilineTi(Ⅳ)arsenophosphate adsorbent for the analysis of organic and inorganic pollutants

摘要

A novel polyaniline based composite cation exchange material has been synthesized by simple chemical route and characterized on the basis of sophisticated techniques. XRD and SEM analyses reveal the amorphous morphology of the material. The partition coefficient studies of different metal ions on the material were performed in DMW and diverse concentrations of HClO_4 solutions, On the basis of high K_d values some significant separations of heavy toxic metal ions were achieved from synthetic mixtures as well as tap water samples by using columns of this exchanger. For the optimum adsorption of dye on the material, the effect of various parameters along with Langmuir and Freundlich adsorption isotherm were examined. The observed result of conducting measurement indicates that the material covers semiconductor range. The photochemical degradation of industrial dyes and antimicrobial activity were also investigated which show significant results than some of the known antibiotics. On the basis of good ion exchange capacity along with photochemical degradation and microbial activity, polyanilineTi(Ⅳ)arsenophosphate can be considered as an excellent conducting material for the treatment metal ions and degradation of organic pollutants.
