| Abstract | ||
| Study of the adsorption of nickel ion (II) with Bis-(acryloylamino-methyl)-Phosphinic acid from its aqueous solution at pH 6 was performed. The effect of different parameters such as temperature and pH values wear evaluated. It was observed that the rise in temperature decrease the adsorption of nickle ion (exothermic). The applicability of the Freundlich model for the data was tested, and the best media was at pH 6. Various thermodynamic quantities namely ΔH, ΔS and ΔG were computed from the equilibrium constant values. | ||
