Modified cross-linked polyacrylamide (PAA) with penta aza tetra ethylene group was used for the removal of Bromocroso green (BCG), industrial dye from aqueous solutions.  Batch  mode  experiments  were conducted  using  various  parameters  such  as  pH,  contact  time,   amount of adsorbent and  BCG concentration and  characterized  with  FTIR  analyses. Fitting the experimental data to different kinetic models including pseudo-first-order,  pseudo-second-order,  Elovich  and  intra-particle  diffusion  kinetic  models  show  the  suitability  of  the pseudo-second-order  kinetic  model  to  interpret  in  the  experimental  data.  The experimental isotherm data were analyzed using Langmuir, Freundlich and Temkin isotherm models. The results showed that the adsorption behavior of BCG on modified adsorbent were well-fitted with the Temkin model at 25˚C. The maximum adsorption capacity was 101.87 mg/g for …
